Foundations of Physical Chemistry

I will also be studying. my name is Deepak Vashishtha and I am your physical chemistry teacher of. So my little ones Kids, we are believers. We the people now Son, I have to become a doctor. very much Today is an important day for you because today is the day of your Your first step is very important in life Are you going to take it? So your choice is to become a doctor I have a dream of cracking NEET It begins in 2026, and today Because son it's your initial first day So there is a lot of it. So today I am a little I'll tell you guys that throughout the year because We have to stay together. Reading your whole year and we are definitely starting the session and have been very important to me as well It's a day son because this session is for me too This is the first live class of . So our people are very We are going to do it well. Very good We will learn each concept one by one from this. all the things We will learn it. Lots of Numerals do. because children are not required to do physical Son, I am scared of numericals. So That fear of yours will completely go away. lots of I will ask questions. lots of concepts will learn. Whatever fear you feel in the physical It was there, but not after today. it would have been very easy Yes son, it is chemistry. You have physical There will be 100% scoring in Chemistry. This I guarantee the thing. because my of kids i am sure i will tell you last 3 I have been taking it continuously for a year. And son Many son selections from this batch also and in physical chemistry I have to aim for 100% scoring. Our target Don't stay below 100%. And you Just see, you will score 100%. Needed? A little sincerity is required. I have to come to class regularly. Regular me I want to meet you. Good afternoon. Good afternoon. Good afternoon my dear little one Little children. So, everyone has arrived. So Let's quickly see which ones are yours The kids have joined. Hello Payal Kumari Abhishek Kusum Yadav Radiant Vision Visionary Rishikesh Shweta Singh Mohd Shik Shivani Pal joins the number of crores 13.5 crore children are already on their own, so let's go Brother Taufik has joined us. So let's go Brother, let's start today's hot one Class. So let's get started. Now I just today because it is first class so my son I I will discuss small things with you people I will do something. Ok? Sir now we need a doctor I have to become one. ok sir we have taken the steps Took it. We have also decided that yes we People are now trusting through the trust batch I have brought complete confidence inside me that yes now I have to prepare. but how are we Do that our perfection in chemistry Come. So for chemistry I will tell you I will tell you. Just give you 5 minutes to listen to me You have to listen carefully and you will see the whole thing If we follow the same thing then it will be 100% yours Son you must be scoring 100% Inside Chemistry. Ok? So let's get started Everyone has arrived. Very very good. So Come on brothers now everybody look now some kids are saying Sir, I am also here. my son me I know there are so many and all the children's names How? But gradually I started to know everyone's name. I will go and remember it too. Ok? Very Excellent. So come on brothers now everyone is very very Look carefully. So what are we to do We are going. Everybody listen to this now be careful. I will tell you some important things first I will tell you what we are Do it? In what way should we do that Let us learn the concepts well. Very Learn to do numericals well. So that’s it. I will tell you a little bit about that. Correct Is? So son some important points which You have to remember the chemistry is perfect To do. Ok? Important Points To follow. Come on you guys think about it and tell me Do we think that these points You should follow this if you want to become a doctor I want to crack neet please tell me quickly What do you feel Sir, after hearing such sermons We have been hearing a lot that do this, do that this has to be done this has to be done absolutely sir We can also start a batch anywhere yes sir even when we used to do it offline then sir this I know that you have to do it like this sir you too Tell me sir, but I know what to do What is it, but sir, I can't do it for two days. There is enthusiasm, if you tell us now then yes we will I will definitely do it, I will follow you for two days I am here sir but since the third day I am the same as before If I become this then it is the children's son There is a problem but don't worry, I am doing the same thing Because I was a kid just like you So how do you avoid that thing then? stealing from the child whatever comes in his mind I will also discuss how to avoid it So first of all I will do the same things if you have NEET I want to crack it, I want to learn the concepts, I have to learn to do numericals. so we What are the steps to follow? So the most First of all, my son, everyone please look carefully. The first thing you have to remember is that I have to attend regular classes. you with me We will have to meet daily. of course whatever happens Are you feeling hungry because our class Timing is 1:15. So let me know at lunch I feel very hungry. No one bread Take it and sit. but don't miss the class Is. If you do it live it will be very good. There is a lot of interaction in it, so it is fun It comes in that. So, son, never miss class. Have to do it. And one word is very useful for children It comes in large amounts. backlog backlog backlog to bhaiya Do not allow backlog to occur. let anything happen God forbid your health ever deteriorates. If I am not feeling well, just lying on the bed I have to watch and listen on the mobile, right? Things. Never miss class. If you take regular classes then you will see that slowly Slowly, my son is getting interested in studies Sweet is that, son, study immediately I am not interested in this. it takes some Time. If you work hard one day, then another Slowly, slowly you will start getting used to it She goes. Then without studying, there is no sleep I am not coming. Ok? Then you need to attend regular classes You will have to do it with me. Ok? Too much Excellent. Now what to do after that? so all People should look very carefully. I have to attend classes regularly. in a good way Concepts have to be understood. how can i I am doing the numerical analysis carefully I have to see it. because your numerical I will develop the solving approach. It Takes some time. it takes a week or 10 days yes son. Ok? So that numerical Solving approach. what do we do after that Is? Which I will ask questions in class. We will ask a lot of questions in our class. Which I will ask questions in the class. now one I got it done several times. what happens son? When the teacher teaches numericals, then the kids One can understand it on his own. Yes dear Sir got it done like this. I understood it. But Let me tell you son, if in numerical We have to bring perfection in numerical solving What to do if you want to develop an approach Will it happen to you? the same questions that I I have done it in class, I go home, that means I will do it at home You must be there. After class in the evening when you are in the same If you revise the lectures then Self practice questions My son. which I did in class if yes then without looking at them then by yourself They have to be solved. what will happen with this You will have to connect the steps. So It is not like these people who just stay in class I have asked the questions and sir has asked me Sir, if you get it done, I will get thousands of questions done But then your question solving approach It will develop, son, when you yourself will You will practice the questions in the evening. Ok? ok sir what other way is there? so let's go Let me tell you the third method. Third way What should I do my little one Children? The DPP you will get is the DPP I won't get it today because today is the first day There is class. Some basic things will happen today. You will also get DPP from next class. Son. Ok? So DPP will give you regular daily Have to solve it. and from here your You will achieve perfection in numerical solving. And the majority of questions will be asked from you Will go. Even if you get stuck in one or the other So, I will give you its video solution, son. I will give it to you. Ok? so at all No need to worry. Everything is your points are going to cover. Ok? Yes. Besides that, what do you want to do, son? To all The important thing is PYQs. But PYQs I don't want to do this daily. I I will get it done in the class also. as if butt The chapter ends. so once the last 15 Last 15 years of the year son PYQs You definitely have to do it. At the end of the chapter. At the end of chapter. I will also do it In the practice class. You also from your Have to do it. Ok? because you will see it son I am looking for the last NEET in the past Questions from last 10-15 years from 10-15 years Just by flipping it around, the data gets changed The concept remains the same. Just change the data It comes. Have you completed any other chapter? To bring confidence in him, if the previous If you are asking questions about 15-20 years old then You will feel that yes, I have understood it. in NEET As questions come I will now discuss them in this chapter that I can burst. So that confidence Meaning that is also needed very much, son. So You will get help from this. Ok? very nice. Now the kids are saying something, sir. Turn up the sound. yes bro the sound is low What? Please tell me the sound. If If it's going well then give a thumbs up Two. If the situation is good then take the higher one Give me your thumbs up. if it is not coming then no write Two. Because son the sound is in my hands Not there. I will tell Bhaiya to go to the studio To the brother that he will increase it. Very Excellent. Ok, that's great. very nice. So Tell me quickly, the sound is coming well. The child is saying sir for the last 15 years Where can I get the questions from? why worry about Are you doing this my son? When the chapters of the class any chapter will end then its I will get it done. Is it okay? to you people I will get you the previous year questions. Ok? Now I will give you everything, friend. Why are you worrying? As much as you It is needed son to crack NEET. See I am telling you that it has been 17-18 years for me. Making children like you doctors. So what does it matter if I don't know about any child? Problems arise. What problems arise? So don't worry about that. whatever you need son I will provide that to you from time to time Time. Ok? don't worry at all Is. Ok? Just yes from my side to myself sincerity has to be maintained and you are Be strong and recognise your strengths. They you have forgotten your powers because your The mind does not get deviated somewhere in between Is. Now look, sir, you told me this, sir We have known this for a long time. Us Have to remain sincere. I have to attend classes regularly. DPP has to be solved. study at home yes sir. We already know all this, Sir. But sir what is the problem? do not follow this gets it. Now, let me talk to you about the real thing. Is it okay? I will take a look. yes the kids are saying Thumb. Look, 80% have thumbs up. Is No? 20% are saying that if the volume is low then the volume is low It's good. So let me tell them more I hope I increase the volume a little more From here. Ok? I tell the voice Of For. I have spoken to the son for the voice. Correct Is? Now my son, I have asked for voice I have said it. There will be noise. very much High. My voice is very loud anyway. You know I'm screaming here So the sound was echoing in the whole building, son. Is. But the sound that should increase from here should also Yours will increase now. Ok? So that 100% No child should face any problem. So let's go Now sir, we know this sir. all of these We have to follow the points. Regular Class Have to do it. We already know this, Sir. Are. I have heard it a thousand times, sir. Because sir It is obvious that I have not done anything unique told. Brother, this is the only way to success, son There is no shortcut. If someone says I I won't say anything, I will recite the mantra for you Or I will tell you a short cut Of success. If there was such a shortcut, son Everyone becomes a doctor immediately yes. There is no one like that. Son look long This term of six, seven, eight months and one year is tireless It requires hard work. With that you become a doctor. Then you will become one. You are full of strength. Bus What do you want? The points I said Yes, you also know this, brother, this is the same Sir, the reader knows all this sir but Sir what is the problem sir you are not following this I am not able to do it sir, what should I do now sir I am feeling very excited when you tell me that This time I will do well in Chemistry I will score 100%, everything is perfect yes sir everything is fine now tell me the voice yes it came right ok sir everything is absolutely right but sir this It cannot be followed. Now I will tell you the reason for that Yes, why don't I follow you? i you I will tell you. Just like two days inside you I am very excited, friend, now I have to do it. I'll start off with a bang. see now What happens? but what is the problem That after four-five days you remain engaged. Big Do you work hard? no i will do it I will do it. and specifically in numericals this Children face problems. whether weather it B. Physics or Physical Chemistry. What This happens when you ask a question line by line. Do you start it? When you ask a question from the line You start doing it and then there are questions It is a lot of fun when we go there. but you You must have seen son, especially physical You must have seen it in chemistry and physics. But As soon as you are asked three or four questions at once If not, what does your mind do? Yours I feel like putting the book aside, my friend. Give. Tell me, does this happen? It happens, right? Look what my Chintu is saying? Saying Yes sir, you are an intuitive person sir. Sir that's right yes sir. When four questions are asked in a continuous line If it isn't there, I feel like picking up a book Keep it aside. then theirs then yours The chat opens. hello babu how are you sleeping yes? So we have to stay away from Babu Sona also. I will come to that point also. Ok? But right now the most important point is in studies, son. Why is interest not aroused? When the son If you are not able to solve the questions then It is obvious that you will gradually become better at studies You lose interest. this is the biggest Reason. Whenever you study physics or physical If you open chemistry then after a while As soon as the numerical stops being what is happening to you guys, son The bio flies because generally what happens in biology is that It is theoretical. you read NCERT Questions are asked from that line only. So Majority of questions are asked to you there. So you enjoy reading the bio a lot. So you become perfect in your bio. But Do you know who is in the selection decision? Where other children cannot do the subjects Would get. Physical chemistry is done, physics If it happens then it would remain your weak position. Is. Because of this there is no selection. So So sir what should I do to avoid this problem Should I do it sir? You said this correctly. Sir You are absolutely right sir in this matter I am so. so my son its the biggest What's the problem? when the concept is not clear Would have been. Solve questions only by memorizing formulas If you try, trust me, trust Me, trust me. So the simple ones from you There are questions which will be answered directly Are formula based. But my son who Logical questions are theoretical nowadays Too many questions are coming. You See You are asking questions with assertion reason statement How many are there? where the concept is checked Yours. You can't achieve anything by just memorizing formulas Can. So we will do the same thing there son Will you point it out? You will see it for the first time, son. If you have many children in your life You may not have read it from me. It is obvious. Isn't it? So you will see that each concept is understood so much We will clear it properly. so much on top of him We will ask questions about all the applications. What will happen if we do numerical? When If the concepts are clear then ask questions from you They are solved very easily. If The questions get solved, son. Gradually you will fall in love with studies. So my purpose is that you love chemistry Will have to get it done. And that will only happen when you The concepts will be clear. one line of You will understand the meaning. Any formula I will not memorise it. Understand the meaning of every formula Where will it come from? what does it mean Is? then look then look how the numerical is left It becomes a child's play. Is it okay? Absolutely. So we will do all this, then you will You will be interested, my son. Ok? So let's go, my son. now with this my son What should we do now? We get from chemistry I have to love. Ok? but sir you Do you want me to love chemistry sir? But sir my love is in another street Sir, he lives in the alley behind the house Sir my love remains the greatest one This is also a problem my son because look I've been 17-18 years, same as you I have been teaching for that many years, son. There is a huge problem in children's education One thing is that we are a little premature They become larger than . we are 17, 18 years old No. we should love studies Because I have to make a career. I want to become rich. I want to become a doctor. Fulfilling the dreams of parents Have to do it. But no, we don’t love it Would. We love each other in the wrong place It starts happening. no my son 1 year for one year at my request You put love in the right direction. I I am telling you whatever dreams you have in life, All will be true. A child like you, son Do big in life and you have full strength Is. Just channel that energy of yours, to that affection of yours, to that love of yours, to that The dedication has to be turned in the right direction. And I am telling you about the things behind You feel that today you are not in the same mood Mostly boys study. They think that yes This is my true love. hey where kiss My son is under some misunderstanding. That Your day will be successful in life, son, all my love I will roam around you. True love is that What your mom and dad do. true love That is what your teacher is doing to you. Because we are the only three people in this world Who want to see you succeed. The rest of the world gets irritated by success, son. So keep in mind that there are only three things in life Yours is true love. your mom and dad who Watching you grow big in life want. and the third is yours Teachers. because i also want you to be Be successful in life. if you will be successful Son, my success also lies in that. So this This is true love. So for these three people For your parents, for your teacher I want to become a doctor. We love to have 6 month 1 year 1 year just right Give me directions. Then the things which you The whole world is running after you today She will run after me. He became powerful. Become the alpha. Today Son becomes alpha on the date. that bike Not by doing tur tur tur tur. today's My son becomes alpha in the date, success You will have more success with this my son I will get it. I am nothing more than that I will tell you, my son. to love studying Is. The concepts have to be understood well. Numericals will be easy. lots of We will ask the questions ourselves in class. The concepts will be absolutely perfect. Bus You should remove your mind from everything and concentrate completely on your I have to apply it on DV brow. With this my Look son, I do not generally give sermons. But because today is the first class so first class If yes, then I have to give directions to my children You will need to decide which direction to go in my children. Ok? Generally these things people We don't discuss it, but I know it This problem occurs with majority of the children There is an obstruction in studies somewhere That's why as an older brother or Accept me as a person like my father It was necessary to discuss these things with you. So let's go I did it. With this my son today Let's start studying. absolutely hold your heart k sit. fasten your seatbelt because You are going on a very amazing flight are going to. We are in the world of chemistry They are going to fly. so let's start. R you guys ready? if all the kids are ready then Quickly give me green hearts with chlorophyll In two chats. There should be greenery all around Because we study with full enthusiasm will start. so quickly all the kids if If it is ready then quickly get the chlorophyll ones I'll shower you with green hearts Son ji. great great great you would have seen it Are. Isha Hameed Saikat Apoorv Priyanshu Ratindra Paul These are my dear children. then a shower of green hearts with chlorophyll Has occurred. So let's start studying. My kids are great at reading I am absolutely ready. very nice. So let's go Son, let's start today's studies. To all First chapter is about some basic concepts of Chemistry which you know by the name of mole concept We also know from this. So we like it very much We will understand from this. Every single thing from the very basics I will get it started. Assuming that you have some It does not come and will be taken to the ultimate level With lots of questions. Every concept of What kind of question is made above, that is our class We will do it inside. So let's start with this Let's do today's amazing class. Start Let's discuss some basic concepts Chemistry. Ok sir. Today you are our value You are going to start the concept. In this What will you teach sir? So first of all So I will teach you what is chemistry it occurs? because we are about to start chemistry We are going. So first of all I I will just give you an introduction as to what we will do throughout the year I am going to study. After that I my I will tell the children about my son matter In. Ok sir will you tell me about the matter? yes My son. After that, I will tell you today The concept of atomic mass and just one thing Let me tell you that atomic mass is called atomic weight also speak. weight and mass in physics There are different things. Whether in chemistry Should I say atomic weight or atomic mass, its meaning It is just beans. The weight of an atom is also We will see. And yes, I can tell you one more thing. Let me tell you one more thing. which is in NCERT The sequence in the whole chapter is something It may happen first, he may get it done later We will get my whole sequence done It may be different from what happens next I should get it done first because it suits me I think that is the best sequence ok If it is there then do not panic that even if the day Match it with NCERT not my sequence It may be different from that but yes, all the things It will be covered but my sequence will continue okay very good and my son then we People will see Aogadros number number brother this So everyone has been reciting it by heart till today. yes sir so much Will you get everything done today? Oh so much fun It will come and we will continue doing the previous Year Questions. So absolutely all the kids If you are ready then let's start studying Are. Let's get started? Sit with your heart in your hands have been done. Absolutely Sir Ji. So let my Let us start our dear children. Now Children are saying sir the first question So this is what is coming to our mind. You are our If you are a chemistry teacher then Sir Chemistry What will you teach me? what is chemistry what is studied? Are any of you Would you like to tell me? What is chemistry? What do you study in chemistry? Tell Tell. Look what one is thinking? My the child is thinking about chemistry sir I have to study. no no crazy this is very half There is an incomplete definition and there is no definition at all These. So what is chemistry? What is chemistry the study of? Let us go Can anyone tell me quickly? think think think chat I will try to answer it. hey both ways There will be communication. There won't be one way only. You also have to get fully involved. So Let me tell you now. you held your heart sit. Stop writing and focus completely on what I am saying. what is chemistry sir? So listen. You have heard the matter, right? Does Matter Matter It happens? Yes sir, I have heard the matter. anything which has some mass and occupy some space It is called matter. Sir, he has been studying since 5th or 6th have been. anything in the world that has any it has weight and takes up some volume Matter speaks. for example this marker It has some weight right? yes some volume too This matter is surrounding me. Absolutely. Yours Your master ji Deepak Vashishth this also matters Is. How? Hey I have some weight and I am some I am also surrounding the volume. yes, your hands I have a mobile phone and a laptop is placed in front of you. that too is matter because it has some weight and It occupies some volume. just this world anything that you see and that It is not even visible. For example, air, You cannot see the air. But air also weighs And air is also occupying the volume. So Air also matters. then the whole universe is in a Since then my son is made of matter only. Is No? Absolutely. So just the detailed matter studies and all his properties We call detailed study as chemistry Are. So what you were thinking was not about chemicals Studying is not chemistry, even chemicals are a matter Is. Hey, not just chemical studies. These What is the marker made of? Brother this is a matter No? What is it made of? his property What is it? This study is also chemistry. what are you and what am i made of Am? What is his property? this study too There is chemistry. So I understood it Chemistry? if it is cleared give thumbs up My little children will give it. come on come On come on. So we have read two points so far Are. What? First of all, whatever you have read now Let us get it written in English. Ok? Everybody look very carefully. To all What is the first thing that matters? Look at what now I have told him the same in English I am getting it written. matter is anything which has Even month? matter is anything we have has some masses and occupy some Space. OK sir. which has some Mass End Occupy Some Space. Say excellent or even volume. Occupy some space. OK sir. Absolutely sir. So everything that we I can see it sir. and what is not even visible It's all matter. Absolutely correct. Now Son Broadley divides the matter into three parts is divided. In many places, there are five I write. Isn't it? Plasma and Condensate But that is a modified form of the gas. So Broadley divided it into three parts goes. Solid, Liquid and Gas. Sir this So we have known that for a long time. butt i am I am proceeding on this assumption. nothing to you Address. Absolutely Sir Ji. So it's ok brother. So Matter Broadley is of three types. Correct Is? Matter is of three types. Now no one does this Speaking Sir there are five. Plasma and Conduit. Hey plasma is made of condensate gas only This is the modified form. When the gas is set very high When taken to high temperature, it turns into plasma goes. like gas plasma in the sun because its very high There is temperature. and when you take too much gas If you take it to temperature then son it will Behaves as a condensate. So Broadley on our Earth is my Son, we know him in three types only Let's classify it. Absolutely. Which ones? Speak fast. Solid, Liquid and Gas. Absolutely right. What is there a difference bro? what difference? Tell me quickly. What is the difference between the three? Difference between the three It happens. which is the constituent particle They create a force of force between them There is a difference of attraction. Arey For Example: you two are friends. one my child yes chintu. I have one child, Pintu. There is no love between Chintupittu and each other. On the contrary, both of them hate each other. So Chintu and Pintu will stay away. Among them Attraction is low. Butt is a friend of Chintu Is. You can accept any name, crazy guy. Chintu's I have a friend named Paglu. From Paglu to his Chintu and There is a lot of love between the crazy people. Both We will stay close to each other. So in them the force of The attraction is high. So just particles What type of force of attraction is there in? This classification has been done on this basis. What do solids contain? Who They contain constituent particles The attraction is quite good. So The particles remain very close to each other. oh What is in the liquid? In Particle the force of attraction is slightly less Compared to solid. so in the particle If the attraction is less, then you will stay away. Well sir absolutely. Right sir. what's in the gas It happens? force of attraction is negligible It happens. Almost none. So brother this is a lot Will stay away. No shape is fixed. Particles remain random. Absolutely Sir Ji. Did you understand the difference? on whose basis is it all Is? It is based on the force of attraction. Absolutely Sir Ji. Tell me, is this a slide? These On whose basis is it? Classification? On Basis of yes forces of attraction Between constituent particles. Ok sir. forces of attraction Between constituent particles. Constituents meaning what makes them up The particles will tell you which particles are Are they there? what happen? Everything will come. Don't worry at all. Say it even Is it cleared? I totally understood the matter sir Went? and detailed study of the matter itself Sir, we talk about chemistry, if the first slide Absolutely in the soul of my children If it is done then quickly come here my son give me a red heart now lalal dil dil de Inside two chats. Ok sir. Chemistry What is? it is the detailed study of it is the detailed study Of matter. detailed study of matter and all of it's Properties. all of it Properties. very nice. Come on, as far as I have read it, come and summarize it once. hey just I would not say. my little ones The children also have to speak from there. both ways We have to maintain communication. Ok? Very Excellent. Come on, let's summarize. As yet What did you read? Every single slide is absolutely soulful It will be published, son. go home to study You will not need any book. As much I am getting it done, give me this much more It is sufficient for NEET. 18 year old I have experience, son. and I know How much do you want? Ok? complete one by one The slide has to be imprinted here in your mind. Bus You will have to go home and ask questions. Correct Is? Let's summarize. First of all, we What is read matter? tell me what would happen does it matter? anything which has some mass end Occupying some space is called matter. That is absolutely correct. the matter on the basis that How to use force in constituent particles Is there attraction? So Broadley has three types of It happens. Solid, liquid, gas. In solid There are the most. because of which the shape The end size is fixed. Lots of liquid The forces of attraction of solids are less Competitions. In gas we believe that It is equal. Absolutely. and of the matter itself We call detailed study as chemistry Are. very nice. to all my children It has reached here. So now let's move forward Let's increase. Now look, it's going to be fun. All Now people sit with their hearts in control. Ok sir. Absolutely. Now, son, I understand this If you want to study chemistry then study the matter It will have to be And my son should first of all The work you did to study well Who did it? Tell me, tell me, tell me. guess who Did you do a good job of studying? First of all Very good explanation about the matter Whatever I gave, Dalton gave it to me. Dalton said There was a theory which we call Dalton's Atomic Theory. and this theory of Through this he learned a lot about the matter Tried to explain. Ok? So let's go now how did Dalton explain Did? So Dalton explained he tried to Explain matter. Isn't it? So through whom? Dalton's Atomic Theory. Ok. Now my son has not got into NEET because of this Question. Had given four statements. Lyrics Which statement of Dalton was not there Is? I have to tell you this. Is that okay, my son? Is it ok sir ji? So let's see it now. How did Dalton try to explain matter? Did you try? So let's get started Are. So Dalton gave his son the first The point is to explain the matter Because if you want to study chemistry then you must understand the matter Will have to read it. So how did this matter son read it? It was the first to propose that the It is a matter of very small size It is made of particles. any matter He said everything in very small words is made up of particles and it Named Atom. So according to Dalton this The marker is also made of atoms. Lamp Vashishtha this is also made of atoms. your hands The mobile I have is also made of atoms. Meaning every matter in the world is made up of atoms Is. Are? Ok? So let's write it down Are. So according to Dalton it is okay? Matter Consist of very very small. Son of this There are four points. You should know everything To. Ok? I will get it all written down. Ok? to the matter consist of very very Small particles. Ok? very very Small particles called atoms. Ok Brother? cold Atoms. Now he has said it. Now, people have He said okay brother the matters are very small Particles are made of atoms. So these atoms How small are they? Do we see them? Atom How small are they? It said that the atom they are so small, they are so small that it cannot be broken down into smaller parts Can. There is nothing in this world smaller than an atom Not there. and understand it in other words Take. Understand it in your own language, son. Yours In language. Hey an atom is so small Is. So what about one atom? I am also a million atoms If I keep it stuck to you, you will look at it with your eyes You will not be able to see it. I can't see it. an atom is Leave it. Even if I stick 10 lakh atoms together If I give you a gift, you won't see it with your eyes you will find it. Son, an atom is this small. Good. So it answered this question from the second point responded to. What? Atoms are so small. Atom Atoms are so small. that they cannot be further that they cannot be further subdivided and Cannot break into smaller parts B Further everything is divided. ok sir that's it I understood it. Now people said this brother People are causing a lot of trouble. People's work It means pointing a finger and disturbing someone. So Come on now again people said everybody is very Look carefully. Now look, one child says Sir it is happening quarter to quarter oh that is from much later It's a thing. The science at that time was so It seemed like a big deal to the people. Correct Is? okay brother. Then the people said that friend Meaning this atom, then every thing is made of atoms. Listen, listen carefully. hey here you come The question is on Daltons. so listen be careful. When people said everything is made of atoms If it remains then it means this marker is also of the atom It is made. Deepak Vashishth also made of Atom It has happened. When people said that the whole thing is about atoms If everything remains the same then it looks the same Why doesn't it look like that? These markers are like brothers It is black and so hard. same lamp Why is Vashishtha not black and hard? Why is it so soft and pale yellow? And Why is it so dark? When this too is of the atom It is made. This is also the same as everything else in an atom's appearance As it should be. This is a logical question. So Dalton shut the people up. It has He said, hey the atom in it is correct. These It is also made of atoms. this is also made of atom Is. But he said that the atom in it is different Types of atoms. The atoms in it are different There are types of . means different-different Different types of atoms in an element There are. For example the atom in gold Those are different types of atoms. In carbon The atoms are different types of atoms. So different elements are of different types I can see it. Everything is made of atoms Is. But different elements are of different types Atom. Is it cleared? Very very good. So My son, the third point, he said this different elements consist of different Elements. That is why they look different. Bus Silver looks different. silver gold different It is visible. Because silver items are different There are types of . Different types of gold items Are of. different elements consist of Different types of atoms. Very nice sir Yes. Well done my lions and lionesses. Different types of atoms. Ok? clear Done? Why are gold and silver different? Can you see it? Everything is made of atoms. butt all in There are different types of atoms. Correct Is? But people asked again. These people are very I am asking brother. Listen to what the people said listen listen now if people say so then one There is an element like gold, listen it is gold You look at the gold from above, it's yellow The gold looks shiny among you If you cut it, son, wherever you cut it, there will also be Likewise, the yellow color will look bright and break People from there also asked why so He said this because he is a particular type of It is an element in which all the atoms are the same If you are of any type then you can put gold in the middle break from the side break from the side. the same everywhere types of atoms are the same everywhere It is visible. Bright pale yellow. means a Particular element consists of same type of Atom. Like it is silver, it is silver. So silver All the atoms in it will be like those of silver. Then you break the silver in the middle, and the top See, from anywhere, it will look the same. Silvery, white, silvery white. Have you arrived? So This was the fourth point. right here in my mind My couplets should be published. Very Excellent. Yes. a particular element any one All atoms in an element are of the same type Are. a particular Element Consist Of consist of same type of atoms. As If there is gold then all atoms are gold It will happen. They will be the same. Same Types Of atoms. very nice. I understood the matter Sir? ok brother say all these four The points have become ingrained in the soul. download it Here, download these. you do it here and there Download things. No son, you are still Anyone used to download apps worth useless funds. If yes then stop downloading it. Now we Just have to download the concepts. Us I want to download the theory. Ask us questions Have to download. Ok? Ok sir. Now Sir, were these four points? not one and most People said it was important okay brother asked different elements There are different types of atoms in it Are. in a particular type of element All atoms are the same. so this one said Are these different atoms of different elements? Can they never stick together? What Different atoms do not stick together Can? Can you just assume that I have an atom? do you have atom dv bro yes bro Kids lovingly call me DV bro what are the atoms of dv bro and the kid These different types of atoms are can't you stick did dalton say yes Can stick to different elements Atoms stick together to form compounds but they always do so in their whole number ratio Yes sir, I don't know that much English. Ambulatory Let me explain. means to say hole The numbers stick to the ratio. accept my There are particular types of atoms. your particulars There are types of atoms. so yes you are my atom your Atoms can stick. Sticking Compounds Will make. but they always do so in whole number Ratio. I mean one atom of mine or one atom of yours It will stick to it only. Or one of my atoms is worth two of yours. Will my two atoms stick to your three atoms? Will stick. never in fractions Will stick. Will stick in hole number. Fraction means it cannot be that my One and a half atoms stuck to your one and a quarter atom. Grandfather Because there is nothing smaller than an atom. According to Dalton. So never 35 atoms Could be. There cannot be three quarters of an atom. one and a quarter atom Can't stick. in whole number ratio only Will stick. I have arrived. Say this statement The most important thing is son Dalton. If If this becomes clear then my son will tell me Now here, black one, give me your heart Because the darkness of ignorance, the blackness of ignorance It has come out. Remove the chat section here Give me your black heart. Very Excellent. very nice. So this is the fifth point He is saying. Difference of different elements Atoms stick together, forming compounds Are. but they always do so in their whole number Ratio. Hole Number Ratio. goss it me Children. wow brother wow. the hearts of my children From the darkness of ignorance which was so black My kids have thrown out the chat section In. O great my lions and you are not lions. Yes. So the fifth point says different Atoms of different elements. different atoms of different elements Do combine with each other. Do combine with each other. Let's combine Different-different atoms. do combine with each other Ginger. Do combine with each other. but they always do so but they always do So. in there whole number Ratio. very nice. My son, besides this Dalton also said some I did not say anything. These are the five statements. These are the five statements. This is totally brain It should be printed in. Statement ones Questions do come up. Write four statements he will give and tell me which one of Dalton's Don't have a statement? then you get all the dalton Atomic theory should be known. NCERT I have given this in my also. So we need to know this Needed Come let's summarize this with me. Come quickly, what does he say? don't there See. Don't look back. Look into my eyes. Look into these eyes, you have knowledge in these eyes What will you find in the sea, my son? Ok? It has become too much. Well then. Dalton What does atomic theory say? Brothers That Matter Isn't it made up of very small particles It is made. They are called atoms. How many? Are they smaller? The atom is so small that There is nothing smaller than this in the world Can. are indivisible and small Cannot be broken into parts. Now In different elements There are different types of atoms. One All elements of particular same type Atoms are same. Like gold is gold Yes, there is a particular element. In Gold All atoms will be the same. only atoms of gold It will happen. Ok? and different elements how different atoms do combine with each other Ginger. but they always do so in their whole number Ratio. Tell me, it is absolutely clear to me To the son? Come on, look now. Now look at my Son, till now whatever we have read, we have seen it all Summarize, tell me what to do, let's do it quickly Tell me if you have read everything till now If I want to summarize again then I have to read here Smile and show me friend you mean both ways should come a lot good let's tell you quickly Two Ashok Raut are asking to read NCERT What will happen sir, don't you want to study, my son, look NCERT is required in biology But it is in Chemistry of Physics. To you NCERT application is there in the paper. There you have to read line by line. There is no need. As much as I'm giving The whole NCERT is involved in it. will be. Do that much. there will be more than sufficient My son. Ok? Very very good. So Come on, let's summarise with me once Are. What is the first thing we read? Matter What happens? matter anything which has some Mass and occupy some space. Matter Three Type of Solid, Liquid, Gas, Force of Based on attraction. Best in solids Lowest in excess gas. detailed of matter We call this study chemistry. So Dalton was the first to explain matter. Dalton Atomic Theory. Matter is made up of Of atoms. Atoms are so small that they become even smaller Cannot be broken into parts. In different elements There are different types of atoms. All the atoms in the same element are the same. Different atoms of different elements Let's combine them with each other. but they always do So in there whole number ratio. Absolutely Perfect my son. Very very good. Now Everyone will watch very carefully. Now You are about to experience the real joy of life. Now Son, real logical things will start. Correct Isn't it? come now. The next half hour is your All the things you have been memorizing till today in life In. Today operate on all of them completely. I will give it. Do it? Ready? Absolutely. Now all get something out of your mind because the next half The hour is going to be very logical. Ok? So let's start my son. Now brother We have to read the matter. study chemistry If it exists then it is made up of atoms. So if If you want to study chemistry then study atoms in detail Will have to read it. To study the atom in detail Meaning all the properties of the atom Know. Meaning of all properties to the atom What? Like weight of atom, size of atom, atom Structure of . so in other words They also say that chemistry is the detailed Study of the atom. because if we talk about atom I know everything about the matter You will know because matter is made up of atoms only It has happened, right? Yes sir. so if only chemistry If you want to study then you will have to read the matter. Matter To understand this, we will have to understand the atom. So You will have to know all the properties of the atom. Like the weight of the atom, the size of the atom, the Structure. So let's look at all the properties of the atom. try to know because this is the There is chemistry. So the first property is How will we find out the weight of an atom? So how does the son acquire the first property? To determine the weight of an atom? Get started. Look carefully. Seems very logical now It is yours. Now life is going to be fun. Ok? Come on sir, get it done. how to Determine the weight of an atom? The first sign of the atom We are starting the property. how to Determine the weight of an atom. Ok Sir. Weight of an atom. Ok sir. Yes. do it sir Yes. Now keep listening. You will say that. Sir Atom How is the weight measured? what are you talking about Are you there sir? Sir, I have remembered it. Complete Listen, stop chatting now. my full focus On matters. Sir how to calculate the weight of atom Are? will you teach this? Sir, we remembered it That is your atomic weight of hydrogen brother Forest. Atomic weight of oxygen is 16. Speak up. Atomic weight of nitrogen is 14. Yes sir we have I have remembered this sir. But son, he is nowhere It must have come from somewhere. So that's what I am to my I am going to tell the children. hold your heart You should sit down. This is going to be a lot of fun. Is it okay? Yes. Now listen. weight of an atom This is what we call atomic weight, my son Or atomic mass. The weight of a single atom is considered as What do you say? atomic weight or atomic Mass. It's the same thing, son. In Chemistry Whether I talk about atomic weight or atomic mass. It simply means the weight of one atom. Sir So how do you remove it sir? We did remember Is. Hey, you never asked about my memory. Reminded you of the atomic weight of oxygen Gaya 16. You never asked where it came from Came? Did anyone have any dream that Say the atomic mass of oxygen is 16. Say the atomic mass of nitrogen is 14. Any It might not have been a dream. so I teach that I am going because I can take NEET from here The question comes. NEET is very important It's a topic, son. NEET asks questions from this every year Asks. Now we will understand that. How Is it taken out? weight of an atom, atomic How are weights calculated? Listen up now everybody Look here. O doctor Shashi Dubey look here My dear child. Is it okay? Yes. Now brother see what Shashi Dubey is saying Is. Let's leave this for later. Isn't it? Let's do this. Come on brother now everybody is very Look carefully. Sir, I have to measure the weight of the atom. So how do you measure it sir? So take this to tell Before that let me tell you some basics. accept my Son you had to measure my weight. You have my The weight had to be measured. So how was my weight measured? Son, be careful from today onwards in this world If you have to measure any thing then first of all one is considered to be standard. A Standard I have to accept it. I mean sir you like me The weight had to be measured. So do you know how it was measured? All the scientists of the world meet together And let's decide together that brother Deepak If you want to measure the weight of Vashishtha then you need to use such a big iron Of This weight is measured in the whole world as 1 kg She will tell me. Have you seen the discount of 1 kg? you have? hey the weight of 1 kilo At the vegetable vendor's shop? yes sir i have seen it 1 Of a kilo. So did god send it in writing This much weight will be 1 kg. No. They Scientists get together and He decided that it was not possible to lift this much weight completely. The world will accept 1 kg. so that's the standard The scientists have decided it. Ok Sir. Scientists have set a standard Decided to take 1 kg. Absolutely. Now the whole The world considers this weight as 1 kg She will agree. Ok sir. Accepted it as standard. Then you had to measure my weight. my weight How to measure? You took my weight away Compares to Standard Weight by 1 Kg and you saw the weight of DV bro is DV This one looks more like an ant than a bro, sir. We compared Sir DV Bro by the weight of the standard and we saw that its weight is 70 times that of its So you said sir you weigh 70 kilos, son This is the basic principle behind measuring Anything. Anything in the world can be measured So the first thing we should do is to accept our standards Does matter. Standard scientists believe Are. OK sir. Then you have to measure my weight Was. How did you measure it? you weighed me down compared it with the standard weight and you Saw the weight of DV Bro. The weight of the standard is 70 times of . you said dv bro 70 They are of kilo. Isn't it? so this is my son The basic principle applies here. If the atom's If you want to measure your weight then first of all you should take a You will have to accept the standard. o so sir 1 kg Sir, why did you not consider it as the standard? When Sir, our standard for measuring weight is 1 kg Is. So is the standard for measuring the weight of an atom I would have kept only 1 kg. no my son No. An atom is so small that we can measure it in our Can't even see with your eyes. If we make this Standards are used to measure the weight of an atom So we cannot compare the weight of an atom with this You could not do it. It is not comparable. so you Think about it and tell me here in chat of thinking Tell me, if the weight of an atom is to be measured then its The weight which should be the standard for It should be very small. being very big Needed? Think about it and tell me quickly. If the weight of an atom If you want to measure it, then accept the standard its weight must be very small or huge? Hey, the atom must be very small of the same weight so that comparison can be made Get it. should be comparable to the weight of the atom yes. Yes very nice. so my little one Little children, we had to measure the weight of the atom. all The scientists got together and together they Standard decided. Ok. And you know this that the standard should be small atom Compared to the weight of . Standard has many I also write the place reference. OK sir. And look at what they considered as our standard. The standard was named by scientists ne kg. The standard of atomic weight The name which he gave was atomic Mass Unit amu short in good ok do you understand now or should i say this nowadays If we have unified mass then amu or unified mass it is shown with u only with u so amu or u it is the same thing don't get confused ok sir ji ok sir ji no problem sir ji we are Sir ji you are very cute kids so its ok Brother, to measure the weight of an atom It was considered a standard and was named Atomic Mass Unit or Unified Mass u amu tell me or u it is same ok sir so sir this Who is considered what kind of weight is this how much weight If I was called amu then listen listen listen to the love Listen to the tune my dear son look here what did the scientists do carbon atom son looks like a carbon atom not even that it will weigh very less okay and that one Carbon atoms must have some weight, right? It is obvious that one carbon atom would be very small He took the weight ok weight of one carbon 12 atoms Ok ok. Ok. It weighs something It will happen, right? Yes. It will weigh a small amount. Yes dear, That's correct. The weight of one atom is. an atom is It is not even visible. the weight of one carbon atom 1/12th part. 1/12th of its weight Did the part. And this weight they He said amu he said amu so my A question is arising in the minds of children Sir, we know this, we have been learning it by heart since childhood yes sir but sir why did you take carbon only sir Look, I am an introvert yes sir why did you take this carbon Why didn't they take hydrogen? Why didn't oxygen replace nitrogen? why didn't you take it, why did you take carbon They I will answer this. It has two or three ridges. All I will tell you. but just keep it like this because After teaching the next thing, then its Reese you'll understand. Ok sir. These Why did you take carbon? Is it cleared? So Brother, the weight of atoms had to be measured. Come here. Eyes on the screen. hello hello eyes On the screen. So son, measure the weight of an atom. Was. So the first thing we need to do is to create a standard I will have to accept it. And he accepted it as the standard. To find the weight of atoms, add Ameya. What is amey? weight of a carbon 12 atom He considered 1/1th part of it as ammu. Now the question is why only carbon was taken? The answer to this will come after one slide. Correct yes sir. Accepted it as standard. now how Did they measure the weight? Let's do the first thing Took it. So how do you lose weight now sir? so listen How did you measure my weight? Full focus Here. Remove your mind from everywhere. Your DV Concentrate on your bro. I am telling Focusing on me is your future The doctor will make you a millionaire and a billionaire. So every Get your mind off the place. All focus is here Give it to me, my son. Ok? Come on now everybody very carefully Look How did you measure my weight? You compared my weight to the standard weight It was compared. Absolutely. same way if a If I want to measure the weight of any atom then my Son, I will have to compare it with the standard. Now let me tell you how the entire focus is here Keep it. Ok? Now assume that I'm telling you son what is the atomic weight of oxygen Take it out. means the weight of one atom of oxygen Take it out. Ok? how did you measure my weight Was it taken out? You took my weight as a standard It was compared by weight. same as oxygen If you want to find the weight of an atom, what will you do? Weight of one oxygen atom is defined as the weight of one oxygen atom. Compare the weight of with the standard weight do it. to be compared with the standard weight My son. Aha, come in a straight line. Yes. What is the standard? 1 /1 * Weight of one carbon 12 atom. Ok? A quantity of oxygen is measured by the weight of the standard Compared the weight of atoms. now sir how is this Did you compare? So listen, now I'll tell you this hmm how did you compare it. keep listening. Your It is not in the syllabus. I will still tell you So that there is no confusion in your mind are. Son, mass is a machine Spectrometer. when you go to college You will see this machine there, my son. This is such a machine that Spectrometer. You can put any element in it Put the relative mass of each of its atoms in my The children tell this. Absolutely. so this Using the machine experimentally This is how he related to me, my son. Pure This came out experimentally. You are such your Can't remove it from. Pure using that mass This is extracted using spectrometry. So When he measured the weight of an oxygen atom Compared to the standard weight using mass spectrometer so what did they do saw? He observed that an oxygen atom has The weight was 16 times the weight of this standard Is. So the atomic mass of oxygen becomes 16. 16 what kilogram what? What is not a village? am you oh yes sir ji because my Standard kilogram was from kilogram When I compared my weight, it said it was 70 kg The standard measurement of the weight of atoms is amu So my son, the unit of atomic weight is also amu So the atomic mass of one oxygen atom is one The weight of the oxygen atom is 16 amu now this means Did you understand, this means an oxygen atom? The weight of the plant must have been 16 times this weight It comes experimentally. ok sir now i understand Did you understand the meaning of atomic mass? If I understand now, for example, nitrogen You have been reminded how much atomic mass is Speak, speak, speak my son sir The atomic mass of nitrogen is memorized 14 14 what amu means the weight of one atom of nitrogen It must have come 14 times its weight only then its atomic The mass is said to be 14 amu. ok tell me the truth What does atomic mass mean? I understood it My son? my son is 16 what am i saying Am? These 16 masses can be observed experimentally. He has come. You just need to know that What does this mean. Mass Spectrometer When using the weight of one atom of oxygen was compared with this weight. so I saw The weight of one oxygen atom is 16 times that weight The fold comes. He did this experimentally I tried it. They can't throw you out. You You can't take it out like this. this is experimentally It came out. Ok? very nice. Now my son Yes, now what is the atomic mass of sodium? It happens? Speak fast. atom of sodium Month 23. 23 what? amu means speak means speak Meaning, tell me. The weight of one atom of sodium is It must have come 23 times. when we had mass If compared in spectrometer then yes He did it experimentally and observed that the weight of any atom is how much of this weight Guna is coming from there son this atomic The mass came out, yes it is carbon Son carbon brother let's go like this I think about you Son, now you understand the meaning of atomic mass My son is numerical about such a small thing The questions have come but still Whatever we have read, tell the truth about anyone If you want to find out the atomic mass, you will find it, right? Ambulatory Now let me tell you the atomic weight of Tell me quickly. I say atomic weight How much of the off carbon has been memorized? Quick Tell me. How much atomic weight of carbon did you memorize? Went? 12. If you have carbon then you can prove it from here Can do. What is the atomic weight of carbon Have you been made to memorize it sir? 12. 12 what? see amu Let me prove it. I say atomic weight Take off the carbon. Come on, how will you take it out? We want to find the weight of one carbon atom. How Will you take it out? the weight of one atom of carbon We will compare it with the standard weight. Yes Sir. So write the weight of one carbon atom on top Will be compared with the standard weight. What is the standard my son? 1/1 * Weight of one carbon atom. Ok? So my son, take the carbon like this Can take it out also. take weight of one carbon Atom. The weight of one carbon atom will be the same No? It was cut. 12 will flip over and come on top. Take carbon, we can prove it as it is Can be done. yes sir. Do you understand now? Carbon Why is the atomic mass of 12 amu? Sir This was proved right here. So any How is the weight of an atom calculated? Come if He went, right? You came, right? So I don't need chlorophyll People give me your heart here green green on then varsha agrahari my son yes so That's why he used carbon 12 ok right? yes let's say the weight of any atom How it is measured became clear quickly Say it for sure it is very good for any atom Comparing the weight with the standard weight yes it comes experimentally, then you just I have to remember that, but I told you to come Why because a question has come up on this I should ask a question on this in NEET. Very good. Now let's do a numerical I I will get it done on this. but before that something Small questions as much as we have studied till now Yes, let's ask some questions on that. Tell me quickly. then look at that thing I will take it forward. Come on. this is my son's first There is a question. what we have read so far Let us ask questions about that. Ok? Very Excellent. Yes. Come on, answer it quickly. Ok? Less On. Everyone can answer. come on me Dear children. You just answer this much. I drink water. Throat is dry Little Like. Less On. Come on. so all the kids did it will be. So look, it is very easy. what is matter? anything which has some mass but does not Occupy space. anything which has a mass And occupy space. anything which neither has mass, anything which does not have mass. So my son B is the right answer which has some It has mass and also occupies some space. These So 100% of the children should be right. These Look at this too Gentleman made a mistake. Ok? Leader Board Niharika is the best officer na Travel. Look at this, brother. So let's do the next question, everybody. Now be careful Look name the particles which make up Matter. Brother, you can do it easily, my son. Don't take tension now. also a very tough question Will come. Is it okay? These are just the beginning things Are. Ok? You feel it now. Ok? Name the particles which make up matter. Come on, Come on, come on. can answer quickly all People. My son must have come. come on come on name the particle this is very easy it belongs to everybody I will stop you Let's poll it is obvious that atoms are atoms, son Makes the matter Absolutely take it, look at the metals brother name in this too The Particles Which Make Up Matter and What It Means Name the particles that make up matter Let's make it. Who makes Brother Matter? Makes atoms. Matter is made up of atoms. Is No? very nice. Check out the leader board. Parvez Junaid I know many children what does it look like in english There is a problem. Like they don't understand what it means I did not come. but no one slowly my Learn to understand the meaning of English while living together Will you go, my son? Ok? Too much Excellent. One child to one son, one child to one child It is important. Ok? So, each child’s Our people will do everything for it. Ok? Now, it is Ok yes brother. Now I want to tell my kids to What did we read? So far we have read this How is the weight of an atom determined? Us Standards have to be followed. of any atom Weight has to be measured. the weight of one atom of that atom Compare it with the standard weight Experimentally, let's see how many times Is. Ok? So my son you will get atomic mass On this basis, we are reminded. So Son you atomic mass starting 20 The elements must be remembered. Correct Isn't it? The first 20 would have been given anyway It is in the paper. Now you guys keep telling me. What is the atomic mass of hydrogen? Speak fast. come soon. 1 amu hey i I will get it done from the very basics. admits it Nothing happens. being absolutely aware of Needed Ok sir. This means the weight of one atom of hydrogen is The weight must have been equal to this weight. One There must have been some sin. Yes right right right sir. What about helium, my son? tell me quickly From. 4 amu of helium means one amu of helium The weight of the atom is four times the weight of the standard He must be coming. When observed experimentally Yes yes yes please tell me quickly about Lithium 7 amu yes Sir tell me how fast beryllium 9 amu of boron 11 amu of carbon 12 amu atomic mass of nitrogen 14 means the weight of one atom of nitrogen Yes it must have come 14 times the standard weight Sir sir oxygen is 16% all this These have been discovered experimentally. But We understood how it came. OK sir 19 amy of fluorine absolutely sir yes yes Say neon fast. It is 20 AM. Ok? 23 of sodium amu means the weight of one atom. very nice. Magnesium 24 let's talk. Keep talking. Me There should be no need to tell. 27 of Aluminum amu is great. Tell me about silicone my son How much will you charge me? 29 AMU Excellent Phosphorus 31 very good I mean now there are some fractions I also have them, I will tell you later why it's ok Isn't it coming now the average atomic weight of sulphur 32 amy absolutely right sir chlorine baby In this, the elder brother is made to memorize 35.5 I will tell you everything, why is it coming yes Well done Ok. After that argon yes sir argon is 40 in my son am good potassium 39 ammu atomic weight calcium also 40 amu ok So up to this point, son, you have to Needed Should be on tips. understand the meaning How did all this come about? do this experimentally Beta using mass spectrometer jis atom I had to measure the weight of an atom, so one of its Compare the weight of an atom with the weight of a standard did and saw like 24 MU of magnesium so this means speak means speak means speak that one The weight of magnesium atom which we have determined as standard It means 1/12 * weight of one carbon atom The weight of one atom of magnesium of that weight is 24 There must have been some mistake. that's why 24 am you wow Sir Ji, wow, my soul is satisfied, Sir Ji, great Great great now let's answer a question I will give you a doubt in your mind, let's go listen listen listen listen very carefully hear from Sir why did you take this carbon in standard Sir why did you not take hydrogen or why did you not take oxygen then one of its Reez, I will tell you now. Now he understands I will come. You me Now tell me both ways of nitrogen There should be communication. of nitrogen Atomic weight 14 is easy to remember or 14.139? Speak Speak Speak. of nitrogen Atomic weight 14 is easy to remember or 14.139 is easy to remember? Speak fast. Oho 14 Easy to remember, right? remember the hole number It is easy to maintain. Absolutely. So listen my son In the beginning, the standard is not I agreed. What was initially considered the standard nor the weight of one atom of hydrogen My son, it was considered standard. Butt it with him What was the problem? If the hydrogen When one atom was considered as a standard Son, when you find out the atomic weight of nitrogen were the weight of one atom of hydrogen Comparatively, that whole number is not multiple Was coming. weight of one atom of nitrogen Exact weight of one atom of hydrogen 14 times did not come. It came to 14.139 times. Oh that isn't easy to remember. Ok. Then Then reject the hydrogen given. then it is considered standard was 1/16th the weight of an oxygen atom Part. Yes. was then considered standard 1/16th of the weight of an atom of oxygen Part. 1/16th part. but same with him There was a problem. When 1/16 * weight of one oxygen atom is When you were comparing it with the weight of an atom, that too Fractional multiple was coming which I remembered It is not easy to keep. But when this was accepted as the standard, the world the weight of most of the atoms when it When we were comparing, their weight was this much The hole number was coming in multiple. which remembers It is easy to maintain. that's why this is one of the Reez said that it was considered the standard. Again Listen to this. One of the reasons. When this weight Compare the weight of all the atoms in the world If this is done then the weight of those atoms will be equal to this weight The exact whole number is coming multiple in comparison Was. Which is easy to remember. so thats Why was this considered standard by my son? Tell me the first reason came. There are other reasons too will also come forward. Did you understand one reason? If When I understood this, I quickly What will the children give me? give me a rose Two. give a rose Two. So let's understand this till here my son. I came. very nice. Very Excellent. Hey Satnam. Satnam is saying Why does potassium have a sur of 39? Atomic Wet. Yes. Why does potassium have 39? Son, I did it experimentally. a of potassium When the atomic weight is measured by standard What is? 1/12 * weight of one carbon When compared, a potassium atom has Weight 39 times that of the standard Came. Oh very good. So come on over to me The children understood it very well Is. Now let us move ahead. hold your heart sit. OK Sir, did you understand that? Now Son, it's a very cool thing. the thing that you You have been memorizing it, I am telling you in the next 15 minutes Son, the most amazing logic of your life Time to understand the things that we used to memorize It has arrived. The next 15 minutes will be the best of your life It's about to be an important 15 minutes. Till today You have seen him everywhere in every book, son He must have memorized it. You will know all those statements today. I am going to improve it now for the next 15 In minutes. then after that a full You will be able to do numericals because you understand things I will come. So let's get started. are you guys Ready? Full focus on DV Bro. yes sir absolutely I am ready. Ok. Now listen now my child I know what's on your mind Has there been any confusion? stop chatting Two. Absolutely focus here, anywhere son He is not responding to any chat. Any Some messages came. Forget the world. think about it For the next 15 minutes it's just DV Bro and It's you, son. and besides the two of us There is nothing in the world. Just give me 15 minutes. You give me 15 minutes. I'll make you a dangerous person I am going to give you the concept. Ok? Start We do. Listen. You son, you would have had this confusion It has been happening. You would have seen if I I am telling you to tell me the atomic weight of oxygen. Listen with full focus. I said oxygen. Atomic Weight Bol. Speak speak speak. sitting Speak loudly. The voice will reach me. Oxygen Atomic weight of. The child is saying 16. 16 What? sir 16 amu yes atomic weight means So the weight of one atom is 16 amu of oxygen Weight of atom yes sir you just told me 16 amu but my son you saw in the books The atomic mass of oxygen will be written in many places it weighs 16 grams tell me the truth have you seen it and There must have been some confusion in your mind that friend This atomic mass is the atomic mass of oxygen means the weight of one atom of oxygen The month should be 16 AM. In books Why is it written 16 grams? So the child's There is confusion in my mind sir this am and Is gram bean a thing? these are in the books Why is atomic mass of oxygen written in grams? of 16 grams. So my son is in the same confusion We will remove it ourselves. Everybody hold your heart now Sit down, my son. This is the confusion. Brother What should be the atomic mass of oxygen? Because atomic mass means the mass of an atom Weight. The atomic mass of oxygen is 16 amu Needed But it must be written in many books That the atomic mass of oxygen is 16 grams. Why? Are amu and gram the same thing sir? Let us check. We will check it. So now I want to clear this confusion of my child I am going. relation between amu & gram. Ok. Sir is this the same thing or not Is it a different thing? Now, sit with your heart in control. relation between amu and Gram. My son is completely focused What is 1 amu here? What is 1 amu? Every child of mine knows this. 1 amu represents this weight What do you say? 1/1 /1 * Weight of 1 carbon 12 atom. Yes sir, This is 1 amu or 1U. Absolutely sir. Now my son, look carefully. I I told you mass is a machine Spectrometer. They don't put any element in it I would calculate the weight of each atom and give it to you Is. So it was detected using the mass spectrometer that the weight of one carbon atom in grams When I was removed in It came to 1.99 * 10^-23 grams. a carbon atom Weight 1.99 * Power of 10 -23 grams. Very It is a big weight. Has a very small weight. Oh very much Has a small weight. 0.00 23 times 0 1999 grams. so small This is the weight of one carbon atom. and this weight Also 1/1 part of it. O where did this come from? Of carbon. hey this Came. Ok. You just have to keep it in your mind. Ok sir. so ok 1 amu one carbon atom He gave it 1/1 th of its weight Solved it. Let's solve it. a decimal move it there 19.9 this moved here so it became -24. Yes Sir. Absolutely. And there is 12 at the bottom, right? Yes sir. Yes. So divide 19.9 by 12 My son. So it comes 1.66 * 10 to the power -24 grams. life to this absorb me into your soul for the rest of my life Children. OK sir. amey and gram bean cheese Not there. Hey, there is a huge difference. amey So it is much smaller than a gram. millions billions It is trillions of times less. Much more than Amay Gram It is small. It is not the same thing. one amu Power of 10 in -24 0.00 24 times after 0 point. hey sir so Sir, AMY is very small compared to a village, crores It is billions and trillions of times less, Sir, am I, then Sir The relation between amey and village is deeply rooted in the soul 1 amu is 1.66 * 10 to the power -24 grams and how it came is also understandable Went. Ok sir. so sir when amu and gram If the same thing is not there then atomic number is mentioned in the books Mass sir, atomic mass of oxygen is 16 Should be amu. 16 grams in books Why is it written then sir? This is the land There's a huge difference, sir. So the atomic mass why are they written in grams in books are you sir? Please tell us sir. our knowledge Increase it. Sir please remove the darkness of ignorance From our lives. Okay, I will teach you. Ok? Now everybody Look very carefully. Listen Vaishnavi Now everybody look at this very carefully. Take. Ok? Yes. Son, this is the weight of one When the carbon atom is measured by mass spectrometer When taken out, it was seen that this is 1.99 * power of 10 -It is 23 grams. a carbon atom brother It is so small that it cannot even be seen with the eyes. So This is the weight of one carbon atom in grams. Brother, it is so small that even an atom can be seen No. OK, that came out of the mass spectrometer. You have to remember this. and a carbon atom 1/1th of the weight when it was solved So this much came. Ok? very nice. Now all people are very careful Look Sir it has been proved. We are confused Was. Is amey and gram same thing? No. There is a world of difference. from amoy gram It is millions, billions, trillions of times less. So Sir when there is so much difference then atomic The mass of any nitrogen is 14 ammu Why do we need 14 grams in many places in books? is it written? atomic mass in grams Why does he write this? So this is confusion. Now I will remove it, why do you do this That is it. Look very carefully. next bus 5 Give me a minute. a very wonderful thing for you The soul of this chapter is that which is going to be proved yes my son. You are sitting holding my heart Son. Is it okay? Yes. Now everybody Look very carefully. Ok? Ok. Now listen. To get involved. very fun I am going to get the thing done. Ok? To get involved. the problem is that the problem Understand first. The problem is that atomic mass Should be in amu. grams in butt books Why is it written in? Let's mean it Let me explain. Sit with your heart in your hands. I assumed Take full focus here, let's have a thought Let's experiment. Put your hand forward. Come on, extend your hand towards the camera. I placed an oxygen atom in your hand Gave. Accept it. I put one on your hand Placed the oxygen atom. Ok? tell me I How much weight do you hold? Speak quickly. hey 16 amu Yes. Hey, the weight of one oxygen atom is 16 amu No. We have already proved this. Yes sir. Yes. Ok sir. So the weight of one oxygen atom is It is 16 amu. now I can write it like this Am. 16 amu oxygen in beta brain Put it all here. This is going to be fun. 5 minutes I may not come to you. heavenly feeling It will be done. Heavenly feeling. Look here. 16 amu oxygen if I gave you that means One atom of oxygen is given. Yes sir. One You have given me the atom. Absolutely sir. Because One atom of oxygen weighs exactly 16 amu. okay brother. So in 16 amu of oxygen There is one atom of oxygen. Absolutely sir. Now everyone please watch very carefully. Correct Is? There are so many grams in 1 amu. 1 amu 1.66 * power of 10 -24 grams. Ok? So 16 can i convert amu to grams Brother. When there are so many grams in 1 amu then there are 16 amu I got 16 * this gram to 16 amu gram Let's convert it into . So 16 amu only I can write 16* Cannot write 1.66 * 10 power -24 grams My son. Because 1 amu is so many grams. So I can write 16 amu as 16 * so Gram. Yes sir, no problem. so much so How many atoms in a gram of oxygen? There will be only one. Hey, it's just the bean. Just convert 16 amu to grams Has converted. Yes sir it is the same. Bus Wrote it in grams. So 1 atom of There will be oxygen. In this many grams of oxygen. Yes. So son, how many grams of oxygen There is one atom of oxygen. Nothing What? It's just beans. how many grams in 1 amu There are. So how many grams of matter are there in 16 amu It's just beans. So there is only one atom in so many grams Correct. So how many grams of oxygen There is one atom of oxygen. So if I If I ask, then what is the amount of oxygen in 16 grams of oxygen? How many atoms will there be? So my son you have completed your sixth In 7th-8th you did basic maths You must have read the unitary method. speak in hindi are the unitary rules. So if I tell you two Oranges for ₹ 4 If two oranges are for ₹ 4 then what will be the cost of six oranges? How much will the oranges cost? So how do you do it? it is divided by this into this It is called unitary method. 2 * 3 = 6 4 * 3 = 12 Sir, two oranges will cost ₹12 if they are ₹4 if they are Rs. then how much will six oranges cost? Divided by these into these this is the way This is a unitary method, it would be the same thing If you don't know it then I will teach you, this is the same thing Let's put things here. so many grams Oxygen contains one atom of oxygen. I know this. so when so many grams If there is one atom in 16 grams then how many atoms are there in 16 grams Will it happen? so this is divided by this yes sir into into into yes sir unitary method exactly sir there will be this many atoms of oxygen in 16 grams of oxygen. ok then solve it We do. Come quickly, see honestly. 16 went to 16. If it comes up to the power of 10 -2 son ji +24 in the bottom 1.66 ok can I write 10 to the power of 24 Cannot write 10*10 to the power 23. Hey One If it is there then it should be added yes sir 10 if from 1.66 You can definitely try it, son, whether it will divide you or not Yes 6.023 AA It looks like a familiar number Looks like a familiar number yes sir sir this is the Agadro number sir We have been reciting it since time immemorial, now see it You will understand the meaning also. This same number we Aogadros speaks numbers. Because these The calculation was done by Agadro. Its What is the meaning? listen listen listen listen to this What does it mean my son everybody now Look very carefully. A Divya Rajput, look here, my son. Ok? What did I say? in 16 amu of oxygen There is one atom of oxygen. yes brother we Do you know what is the atomic weight of oxygen? Speak fast. The atomic weight of oxygen is 16 amu its ok sir. So one oxygen atom has 16 amu then I wrote down 16 amu in grams Gave. How? 1 amu is this many grams. So What can I write to 16 amu? 16 * 1.66*10 power-24g. Ok sir. talk It's beans. So in so many grams of oxygen there is only one It will be an atom because it is the same. this bus Converted into grams. Ok sir. So In this many grams of oxygen, one atom is 16 How many atoms will there be in a gram of oxygen? So These are divided into these unitary Method. So son if you cancel then 16 grams 6 * 10 to the power 23 atoms in oxygen It will happen. And my son named this number Given one mole. Son, nothing is worth anything Would. One mole This number is called one mole means to 6.023 * 10 to the power of 23 it could be anything Is. If I tell you that you have a price DV is bro. So how many DV bros are there Son? 6.023 * 10 to the power 23 so this is a dream Agadro did not come. this is simple I had done the calculations. butt what does it mean Sir? So see it is proven. look at this Look at the application and now understand the meaning of this statement Of. If you are writing atomic mass in amu So my son, what is the weight of one atom. Listen carefully. If any element of If you are writing atomic mass in amu then its The weight of one atom is. but if its atomic number If you write the mass in grams then one atom has no weight. 6.023 * 10 to the power of 23 atoms weight Is. If the atomic mass of an element is amu If it is written in it then it is the weight of one atom. But If its atomic mass is expressed in grams I will write. Don't panic, son. who understands I did not come to prove myself even for the next atom I will do this. Ok? Now listen, if that The atomic mass of any element is expressed in grams If you write it, my son, the weight of an atom no that is the weight of one mole of atoms and one mole This number is called the one which you know till today I had been reciting it by heart. hey aogdro has no dreams had come. This was a simple calculation. Let us go And what do you all do now my son? Look very carefully. me and I prove this for the element. Don't worry at all, my son. Ok? I would prove this again for one element I do it. This time you will get 100% My son, you have to understand. Correct Is? Even those who don't have it, have got the majority. Those few who did not get it, they will also get it. Let us go Let's do it again. The confusion was that Atomic masses must be in amu. But Why is atomic mass written in grams in books? Are they written? Many places. Now I'll go again I prove it with this. Now think that I have given you Given an atom of nitrogen. Now all the kids You will say, I gave you one atom of nitrogen Son, I have told you. How much weight has been given? How much weight has been given? hey 14 amu hey amu one We have already told the weight of nitrogen atom. 14 amu is fine. So, in 14 amu of nitrogen Look again very carefully. 14 amu Nitrogen contains one atom of nitrogen Is. Right? Right? Correct. Do it now. Now Convert amu to grams. 1 amu = 1.66 * Power of 10 - 24 grams. So 14 amu only I can write. 14 * 1.66 * power of 10 -24 grams. Yes sir. Beans It's the weight. Just write the amount in grams Gave. Yes sir. So how many grams of nitrogen There is only one atom in it also. Oh, because that's the weight Is. Just wrote 14 amu in grams. Ok. So how many grams of nitrogen in There is one atom of nitrogen. yes I know This is for me. So when so many grams of nitrogen One atom of nitrogen in a molecule is 14 grams How many atoms of nitrogen are there in nitrogen? Will it happen? Unitary Method. these are divided by these yes Sir this this inu this is very nice yes sir so many atoms Everyone will be absolutely right now. Look at this very carefully, my son. gone absolutely absolutely absolutely because how Brother, do this in so many grams of nitrogen atoms so how many atoms are there in 14 grams of nitrogen So this divide by this into this exactly Sir. Now solve it again son. 10's again The same number came from. this goes up to +24 Went. Now if my son solves this So this son will become the same again. 6.023 * 10 to the power 23 nitrogen atoms. Oye hoye hoye hoye. a very brilliant statement Which you used to repeat till today my child. Now There is no need to memorize. Now you understand for the first time I came. If the atoms of an element If the weight is written in amu then the element is the weight of one atom. but if the If the atomic weight of an element is expressed in grams If I write it then a single atom has no weight. That's 6.023 * 10 to the power 23 the weight of the atom Is. and this number is called one Mole. One mole says my son this number To. Now you don't become a doctor, I will take you I bless you. I bless you I'll give you a price of money so that you become a doctor Earned. This is a small number. no no one value You will earn money by becoming a doctor. Ok? So This is a huge number, my son. So Agadro did not have this dream. this number to They say one mole. This could be anything. I He said you have a lot of friends. Now look what He is asking. Sir tell me do you have a female friend One pound of mine? Oh no, don't go there. Come here. I said you have a price If there is DV bro then how many DV bros are there Are? 6.023 * 10 to the power 23. this number is Forest Mole. Anything can happen. I said You have a lot of money. so how much rupees Are? You have 6.023 * power of 10 for ₹23. I said there is one mole of atoms, so how many atoms Is? 6.023 * 10 to the power 23 I said May you have a priceless marriage Went. If one mole of marriages takes place then take 6,023 * Power of 10, you have had 23 marriages. So This number is one mole. How did you come? To understand Came? yes sir. We have proved a very great thing Is. Everyone, sit with your heart in your hands, my son. If the atomic mass of any element is amu If it is written in it then it is the weight of one atom. But If we measure its atomic mass in grams If you write it, it will not be the weight of one atom of it Is. No no, one mole of atoms has a weight. A very wonderful statement which you will remember till today I had been reciting it by heart. Son, we have proved it. Tell me if you understood these things at all So, I will get the numerical done. Now now its This is a very powerful numerical application. We will ask lots of questions about this. If If I understand this far then my son He will show it with a smile. lots of laughs here Show it to us so we can understand. one we A very wonderful thing has been proved here. Many children have this confusion. These I cleared it. the statements we memorize were I understood. if there is any If the atomic mass of the element is written in grams which we also call gram atomic mass if it is then it means it is not the weight of an atom Is. The weight of one mole of atoms of that element Is. See, I have proved it again and again. If the atomic mass of nitrogen is written in amu then Weight of one nitrogen atom. of nitrogen Atomic mass if written in grams is 14 grams Nitrogen does not have the weight of a single atom. One Mole is the weight of nitrogen atom. very nice My Lions. Very Excellent. Great great great. I am so so Proud of you my kids. very nice. Now Son, from what I have read so far, I will get it written statement wise. then you I am a great question this statement is My son is the soul of the chapter. See more We have proved it. I haven't learnt anything by heart. This brother, this is DV bro point. Ok No? Questions in NEET from DV Bro Point It keeps coming. Remember this throughout your life. okay brother? Ok. What now? Everybody listen Take. Ok. Yes very nice. kids saying Sir, you are just teaching. You are not talking sir. hey things do. But today is the first class. So today we Some concepts, some good things to learn It is necessary, son. Day 1 Conceptual Clarity is very important. to talk to We have the whole year for this. Correct Is? Now everybody be very careful Look Correct Is? What am I saying now? Now if this is the case You can measure the atomic weight of any element in amu I will write it. atomic weight if you have calculated it in amu If it is written then it means that it is a part of that element is the weight of the atom. atomic weight in amu Represents the weight of one atom represents weight of one atom But if you measure atomic weight in grams You will write but atomic weight in Grams. If the atomic weight of the same element wrote it in grams, this is one mole of atoms Shows the weight of . Represents Weight Off One mole of atoms means 1 mole 6.023 This number is called Paglu Ek Mole. ok now let's do it more clearly it means a lot It is important. Everybody pay very close attention now Look at me, my son. yes listen listen listen hold my heart and sit Son. Now listen to me very carefully Let me explain. A lovely thing and fun to watch Full focus will come within 2 minutes Things have to be summarized, my son. How did I tell you that it is sodium? sodium sodium I said 23 amu we know the atomic mass of sodium how much is 23 Atomic mass is written in amu, it means this This is the weight of one atom of sodium. Sodium If the atomic mass of any substance is written in amu If you are, then this is the weight of one atom of sodium. But if I say 23 grams Sodium 23 grams sodium is then its atomic number Mass is written in grams. So 23 grams Weight of 1 mole of sodium atoms in sodium That will happen. So there will be 1 mole of sodium atoms. well a mole means for numerical Let's write down approximately sixes, 6.023 ok the weight of 1 mole atoms of sodium is 23 Gram Bol I understood the point I understood the point very nice o Great come on come on now I'm asking you I didn’t ask, my child told me hey listen listen listen yes yes I told you If helium is 4 amu then tell me how much helium What is the weight of atoms? Then I said 4 grams Helium. We know the atomic mass of helium Four. Atomic mass is written in amu. So This is the weight of one atom of helium. of an atom This is the weight of helium. but its atomic Write the mass in grams. So this is a A mole of helium atoms weighs Re and one mole Means 6 * 10 to the power 23. very nice My son. O my lions, you have made my heart happy. I am so so proud of you. come now. These We became absolutely clear conceptually. Tell me if it is clear? It has been cleared No? So all the kids now hurry up and tell me Give me pink hearts. Then I make it Just two or four sons of some numerical last Let me ask questions. Is it okay? Yes. Ok. Well done Apuva Singh no one My lion Apuva is saying, Sir I am hungry. My son, I am also hungry. I My son hasn't even had breakfast since morning. Is it okay? but no one cares about studies, studies My son, I am going away from hunger, thirst and sleep Needed but what do you do, you are hungry and thirsty You try to drive away sleep by getting caught up in something else. No, all this has changed from today. Now you are DV It's Bro's baby. Now only your hunger Thirst and sleep are dedicated only to studies will be. Ok? Very Excellent. Now, my dear children, now Let's ask some questions on this. Now See, this statement becomes very numerical. Are. I will get it done in lots and lots of them. Let us go Now let's ask the question. the next 5 minutes are Last K. The last 5 minutes were a lot of fun will come. Ask me questions. come on come on Come on. yes come on tell me quickly. Oh this is a lot This is a good question. I will tell you soon my lion. Come on. all kids can do this Are. Yes. Great great great. lots of My son will ask questions. you are tension I will not take it. Today might be the first class. So today I have told you a little about that The concepts have been explained. Ok? full to the brim We will do it numerically. lots of questions I will do it my son. because the first 15 Day is my purpose, you are in numerical Make me a hero. Don't look into numericals You will keep doing it slowly, son. I have to be perfect. It takes 10 to 15 days Are. But you will do it with me continuously, right? Then See how strong is his hold on numericals It will be yours. Is No? Come on. Answer quickly. Now let me show it to my children. Everybody look very carefully. Ok? What is 1 u? tell me fast. What is 1 u? tell me fast. 1.66 * 10 to the power 1 amu Tell quickly. Yes, this is absolutely correct. 1.66 1 amu 1.66 * 10 to the power -24 grams. oh yes Sir, how is this possible? then all is I can't do it. Isn't it? And there is no other option It seems just right. exactly 1 amu means 1 u AM 1.66 * 10 to the power -24. oh yes sir Yes. Tell me did such question also come in NEET Is. 95% of the kids hit the mark. 100% did Why didn't you kill my lion right now? My son is okay now let's see the next one Sit with your heart in your hands my son now enjoy it's coming ok right Yes Ok, now see, this is a very nice question. whatever my child will do i am telling the truth I am going to give him the best in the world valuable thing reward I will tell you what will you give me sir and this The one who asks the question is my child Son, he has the courage to go to AIIMS Delhi. Come on now beginner basic-basic questions Is. Will also ask a lot of food-related questions. This time I thought about it. means like this i Should I make you pass NEET? jee mains Can the questions of JEE Advanced be solved? You guys will give it. Is it okay? absolutely great Excellent. will start with the basics because Ultimately a good question, even from the basics It starts right now. Basic Strong It is necessary to have it. Correct Is? Now my son the question is this. Mass of One atom of an element is 8 * 10 to the power -2 grams. this is equal to aji ye to wahi Done. Now we know brother how many grams If it is in amu then I am asking how much will it be? Oho everything is done through the unitary method. See Don't panic. Do you know what is 1 amu or 1U? Is? 1.66 * power of 10 -24 grams. Yes sir. Yes. I know that there is 1 U in so many grams Is. When there is 1 u in so many grams, then how many grams How many U's in me? Everything is unitary. Aji Unitary What is? Hear Three samosas, three samosas for ₹5. So how much do six samosas cost? so this is divided by In Innu This is good sir, three samosas for ₹10 and six for ₹5 Samosas are divided into these Unitary method is the son of entire chemistry We get out of this. to memorize any formula There is no need. Unitary method is 90% He will get the question solved. yes see how I know there would be one U in this many grams Is. ok so 1.66 * 10 to the power -24 There is 1 amyl in gram. ok so this If you have asked then how many AMUs are there in so many villages Will it happen? So in this many villages you asked the same thing Is. yes then how many u in this many grams Will it happen? unitary method same thing or an orange 2 oranges for ₹5 how much is this divided by This is the same thing, there is one AMY in so many grams How many amu are divided into so many grams? bye into this into this yes very Good sir, you will come in so many villages Yoyo 8/1.66 Yes I did not give the poll did I? Take Take. Take the pole. Take the pole. Ok. Yes. then solve Do it and tell me quickly. very nice. Quick tell me from. So my children must have arrived. very much It's easy. 4.8 u. Oh yes Sirji. Yes. wow brother wow. My kids have become so intelligent Are. Ok. So you have to go to AIIMS Delhi Everyone is full of strength. telling the truth I am. and my kids go to AIIMS Full of it. Is it okay? Yes. So 93% got it right Killed him. o my kids are learning great Are. I'm so so proud of you guys and Girls. Let's do the next question. Ok, now this is a very good question. would we like to do it? Come on, try this and tell me. Let's see this. Or else do this. Let us go do this one. We will do more now. We will do it in abundance in the next class. Do this now. what is the come on come on come On my lions. Tell me quickly. what is The charge of 96 amu? quickly Tell me. what is the charge of 96 amu of Sulfide. You must have said come on come on come on. Take care. S2- Let me give you a hint Am. Listen Listen Listen. S2- Right? So its I mean look at the sulphur atom as a hole It is neutral. yes add two extra electrons to it When I gave it, I got two negative charges. atomic mass by adding and removing electrons It doesn't make any difference. Because The mass of the electron is negligible Son. Ok? So the atomic mass of sulfur is neither the neutral ion nor its ion The atomic mass will also remain the same. Ok? Why? because by adding extra electron mass doesn't matter because The weight of the electron is negligible. Less On. So let me get this done now. Let us go I told you just this much. Ask in Coolum Used to be. You know, everyone knows this. No Please keep this address in mind. on an electron How much charge? Speak fast. 1.6 * 10 to the Power-19 Coolum. Yes sir. we have been doing this since childhood I have been studying sir. very nice. One Do you know how much charge you have on an electron? It happens. Here, sulfur has two electrons Come. Atom as a hole is neutral. Two If we take extra electron then it will have -2 The charge has arrived. then one sulfide ion per two has equal charge to that of the electron. Yes sir. One Sulfides are molecules of sulfur with two electrons on one atom. There is equal charge. so he is asking what is the charge on 96 amu of S2- 96 amu of two electrons on a sulfur atom There is equal charge. So look at 96 amu. How many sulfur atoms? And it's done ok sir. Now let's go I will get it done. I make my kids To. Look very carefully. atomic of sulphur tell me mass 32 i know atomic mass When written in amu it gives the weight of one atom. yes sir so 32 in amu sulfur Yes there will be a sulfur. yes sir yes a sulphide ion will be. Absolutely right sir. a sulfide ion because atomic mass is expressed in amu If we write it, then one sulfide ion in 32 amu will be How many ions in 96 amu? how many in 96 amu ion? this is divided by this into this yes Sir. So how many sulfide ions are there in 96? 32 * 3 = 96 so three sulfide ions are 96 amu In. Yes sir Yes, you know there are two electrons on an ion. Charge equal to yes sir. Yes yes sir. an ion How much charge per sulphide? Two equivalent to an electron. on an electron So much charge. then how much is there on two electrons Charge? Its double. its double yes sir yes If this much is required for two electrons then make it 16* 2 = 32 3.2 * power of 10 exactly Sir, two electrons have this much charge double the charge of the electron is exactly one in sulfide because two electrons Equivalent charge on a sulphur to the power of 3.2*10 -19 coolam is charged and I know 96 92 amu contains three sulfides. So when a sulfide But if the charge is equal to two electrons then there are three How much will be in the sulfide Unitary Method this yes is divided by this yes into this ok cool it down this much 3 * 2 = 6 3 * 3 = 9.6 * 10 to the power -19 Coolam awesome. C must be the right answer. did you tell the truth To understand? Oh, don't lie. saw this see this What a mess my child created. big nice There was a question, right? It was a good question. See Nothing. What did he ask? what is the Charge on 96 amu sulfide? I said How is sulfide formed? Brother Sulfur Atom has two For electrons, two negative charges come Went. by gaining and removing electrons, mass Doesn't matter. of one atom of sulphur If we know the weight of 32 amu then 32 amu of sulphur has a It will be an atom. So, there are three atoms in 96 amu of sulphur. It will happen. Removed from the unitary. so yes sir There will be three atoms each. Means three sulfides The ion is 96 amu in size. two in one sulfide charge equal to that of the electron. an electron So, there is so much charge on two electrons. Double. Yes. yes right right right so my Son, give this much charge to one electron So much on electron, yes sir, yes so one If the charge on sulfur atom is so much then in 96 amu three sulphur so how much is this on three sulphur Divide by this into this Well done, tell me the truth, now another question like this Should I ask you another question like this? My child will achieve perfection at last I am asking you a question, after this one again Every one of my children has to achieve perfection ok sir give me one more question. Let me go Now I am telling you to charge on and tell me quickly. Charge on I won't tell you. my child has I have to tell you. ok sir charge on ok yes yes Should I ask? Should I ask? Yes. 28 amu charge on 28 amu nitride ok ok come on come on come on quickly I will tell you my son, I did not tell you The child has to tell 6 * 1.6 * 10 power -19 OK B3*1.6*10 power -9 19 coolam coolam This should all be alright soon. These Everybody should be right. 1.6 * 10 power -19 Coolum. Charge on 28 amu nitride. ok d Nun. Come on my lions. quickly Tell me. Now everyone has to do this. Look at everyone's will form. This will happen to everyone, my dear children Charge On 28 First Look At A Nitro Me Hint I am giving it to everyone, I want to give you a hint I have been my Son, how can there be three negatives on one nitrogen? Nitrogen must have gained three electrons If you took it, then it came negative 3 times, okay sir One nitrogen has three electrons The charge on a nitrogen atom is 28 amu How much nitrogen to remove Atom? atomic mass of nitrogen in 14 amu There is one nitrogen atom. So in 28 amu See how many and one nitrogen for three has equal charge to that of the electron. Tax do it to me Son. Look my child, speak honestly. Today there are a lot of things like that in class As you keep asking questions about Avogadro's number Keep doing it. I am saying this until You are solving it. But there are a lot of such These are the things which you used to learn by heart till today. like you thought you knew the Agadro number No, where did this come from? but today you are simple After doing the calculation, I found out that this is nothing It comes from the relation between amu and gram. If Atomic mass is written in amu For an element, it measures the weight of one atom of that element. It is showing. If an atomic number of the same element If I write the mass in grams then it will have a It is not the weight of the atom but the weight of one mole of atoms. Isn't it? then everything became absolutely clear To my son. Ok? very nice. See how easy it is. can my Son. done it will be. Now we will all watch very carefully. Listen listen listen son of nitrogen Atomic weight 14 14 amu has one atom so 28 There are two atoms in amu, yes sir. So here, 28 amu contains two nitride ions. Yes sir. Yes Absolutely. one nitride has three electrons Charge equal to . then how much per nitride Charge? equal to three electrons. 3 * 1.6 Because this much happens to one electron. Yes sir. How many cool charges on one nitride equal to three electrons. So in 28 amu So two nitrogen. Yes sir. because 14 amu There is one nitrogen in it so 14 * 2 = 28 so 28 Two in amu. So when one of the two nitrides equal to three electrons on nitride The charge would be two nitrides in 28 amu so how much is this charge Divided by these into these yes lo ji ho gone 3 * 2 6 wow sir ji wow wow sir ji Wow I think all my kids will become champions I am so now I understand it well O very good, very good my lion, make my heart happy My son, this is the last question for them My son you have to do it with yourself also but Tell me honestly my son, today we I will do just this much, today was the first class, okay No, but honestly, my kids will tell me. Every single thing of the whole class, just come into the soul Let me summarize you for 1 minute, listen, summarize for 1 minute Let's do it, you will feel each and every thing It has been downloaded into the mind. Ok? Yes. And this is just the beginning. Right now it's full We will discuss all our question concepts. Ok No? Yes. Now everybody pay very close attention Look Ok? o cute candy look here Take. So listen, let's summarize it once Son, what we studied throughout the class today. Come Come let's summarize with me. First of all matter anything which has some mass occupation Isospheric. Solid, liquid, gas, right? And My son studies chemistry. His What does Dalton's atomic theory say after this Matter is made of atoms. smaller than an atom and can not help it. in different element Different types of atoms of a particular element All the atoms in it are of the same type. Different Different atoms of the elements combine. but they always do so in their whole number Ratio. After that we weighed the atoms How to remove it? So first of all, the standard I have to accept it. to find out the weight of an atom The standard considered for this is called 1 amu or u and how much is it? 1 amu 1/12 * weight of one carbon atom. Carbon is the standard Why did you take it? Why was this considered the standard? Because due to this when any corner of the world When we were comparing the weight of atoms The exact whole number was coming in multiples. Yes Sir. So how to find the weight of any atom? Are? One atom of the atom whose weight is to be measured Compare the weight of with the standard weight Let's do it experimentally. and what comes from that That is our atomic weight. Very very nice. After that my son, we saw again that it was ok Atomic masses come in amu. Then we Did you see what gram beans are? no ground sky There is a difference. amu my son is very from gram It is small. 1 amu 1.66 * 10 to the power -24 It is a gram. Then you were confused that Atomic masses must be in amu. Books Why are they written in grams? So V Have proven one thing again and again. If The atomic mass of an element is written in amu If it is then the weight of one atom is. butt atomic If you write its mass in grams then one It is not the weight of an atom but the weight of one mole of atoms My son. Ok? Yes sir. So this There are too many statements right now Numericals are still pending, my son. Ok No? So I think all my children will love it very much I understood it well. Is it okay? Yes. Very very good, my son. and telling Slowly slowly my son things It will become easier. Is it okay? Bus Persist with honesty. Look at this, son What am I even doing? can simply memorize it Yes, I made you memorize this statement. These Made him memorize the statement. Butt not my son Nowadays, the paper has changed. now the ones who memorize Nothing will happen. behind everything Reason. Look, I have memorized everything No. I gave you proof of everything Is. And this is the way by which son is now yours There will be a selection. and I know you guys will Will you take it? Is it okay? Yes. Ok. very nice My dear little children. Brother, I hope for my lovely children I understood everything. Is it okay? Next Is he in class? So what's the homework today? Come, I will give you your homework, my son. To. Ok? Should I give it to you? Let me give you the homework Am. Let me give you a question. Let's go a lot Look carefully. Is it okay? you to me have to tell Calculate number of atoms. Number of atoms. You have read a statement. on its basis What should I tell you? If someone's atomic mass If written in amu then it is the weight of one atom. If If we write atomic mass in grams then one Weight of mole atom. yes, i am saying calculate number of atoms in Yes, I have to tell you these. I did not Tell me 8 gr. Oxygen, it is like this. if yes then If it's not great then it's great. To do it unitary. Isn't it? Trying to do it unitary. We can also know Agadro's number as 6*10 to the power 23. Let's write it down. Ok? Good. B Yes Yes ok si ok d none of the above none of the above come on so its ok my son with this I hope my little children today I understood everything in class and just like that My son will keep studying slowly I am telling you the answer. This is a slow one. Son, this colour comes on slowly. Dangerous The one that goes up is DV Bro's. Is it okay? And very nicely and perfectly to you son Everything has to come in chemistry. Ok No? So study well and understand the subject If you want to love, you have to learn. Ok? So I hope my son is well with everyone I understood everything. Is it okay? so the next You will get some new concepts in the class with. And they have a lot of work to do on this concept right now The application is pending. What I taught today was that I have proved that statement There are many applications of the statement right now There are questions remaining. that next class I will do all our work. Ok? So let's go see you in the next class my love Children. Isn't it? then till then ok tata Bye-bye. Love you all.
