Polyatomic Ions Mnemonic

Nick the camel ate a clam for supper in Phoenix now really important stuff the underlying letter represents the symbol of the element okay so let's look at the underlined letter for each one of them the letter N Nick what uh element in the pureon table we're looking at is nitrogen the C for Camel represents carbon the symbol for carbon CL okay um and it's not written as C capital L it's C and lowercase L and that represents chlorine the S here for sulfur the P for phosphorus okay so that's what um the underlined letter in each one of those words stands for the consonants okay and those are uh designated with each word okay they are the well in written in black the consonants represent the number of oxygens that are present with the symbol that starts off each word and the vowels represent the number of negative charges that follow okay and we're going to uh to see that breakdown right now so let's move on Nick okay the underlined letter is n okay how many consonants does uh the word Nick have it has three how many vowels one vowel so what does that all mean so how do we put it all together well we start off with the letter N the nitrogen the number of consonants represents three oxygen so we're going to write n and then an O3 the vowel now represents the negative one charge and because there's only one vowel okay in the word Nick there is only one charge and that charge is a negative charge Nega one so now we don't read it as nitrogen oxygen 3 we read this as the following nitrate notice how the name for the nonmetal part used to be ID okay that was the IDE and that represented the non-metal but in terms of polyatomics at the part that we said Nick the camel ate a clam for supper infinix that eight is represented in the name of the polyatomic okay so we don't have a normally we'd have nitride but that was without the oxygen okay nitride okay whatever the N was -3 in according to the periodic table that's nitride but the nitrate the the nitrate is NO3 with the -1 okay so let's look at the uh the next example camel the underlined letter is a c number of consonant there are three number of vowels there are two so how do we put it all together well we start off with the letter c how many consonants well there are three consonants so it represents three oxygen So Co 3 and how many vowels there are two vowels they represent two charges two negative charges so co32 okay uh it's a derivative of carbon okay but the ending has an A so it's carbon 8 we don't make reference to the oxygen the at ending here tells us that oxygen is present with whatever is in front of it carbon okay or with nitrogen as it was with the example before that next example clam underline letter or should we say letters CL number of consonants three number of vowels one so how do we put it all together well CL there are three constants so three oxygens number of vowels there's one so one negative charge so negative one so what element um are we making reference to we're making reference to Chlor uh the chlorine but because it's a polyatomic and it has oxygen present we call it chlorate okay uh supper okay the underlined letter s number of consonants four the number of vowels 2 so how do we put it all together well start off with S four consonants four oxygens so s so4 two vowels two negative charges -2 and because we're making reference to sulfur uh and the at ending so we call it this entire compound here s so42 we call that sulfate and lastly Phoenix please uh very important that you know how to spell the word Phoenix same thing goes with supper okay we don't uh forget that extra p uh so Phoenix uh underlying letter is p number of consonants four number of vowels here are three so how do we put it all together well start off with P okay four consonants four oxygen so P4 three vowels three negative charges -3 okay in the name it's the derivative of phosphorus so because there's oxygen present we call that phosphate okay so some other polyatomics that don't follow the Nic Theo rule that you must memorize nh4 + one or just positive is the ammonium ion okay so this we're going to treat that as a metal and and then the O Negative which is the hydroxide ion okay so those are the only two that don't really follow the U the Nick the camel rule okay some others are what we call the hydrogen polyatomics how do we know them well if we look at the charges we look at the charges ignore the hydrogen the minute we add hydrogen carbonate alone just carbonate without that okay was CO3 -2 but the minute we add the hydrogen in okay the minute we add the hydrogen in we are also going to take away one of the charges okay if we look at the next example here sulfate without the hydrogen was s so4 -2 but now that we add the hydrogen okay we remove one of the charges okay and same thing goes with phosphate when we looked at phosphate without the hydrogen it was P4 -3 but the minute we add hydrogen to it we drop one of the charges okay and this the hydrogen phosphates only works with carbonate sulfate and phosphate we could not drop the charges for nitrate so you not have a hydrogen nitrate um or a hydrogen chlorate so those are two of the ones that you're not going to find hydrogen polyatomics for okay moving on
