Describe the trends for atomic radii across the periodic table.
Press to flip
Atomic radii increase down a group and decrease across a period.
What is the trend for ionization energy across the periodic table?
Ionization energy increases across a period and decreases down a group.
What are net ionic equations used for in chemical reactions?
Net ionic equations exclude spectator ions to focus on the actual chemical change.
How is reaction order determined in kinetics?
Reaction order is found by making methodical changes in concentration and observing the rate of reaction.
How are pH calculations related to acid-base reactions?
Calculating pH is crucial in understanding the strength and nature of acid-base reactions.
What is the significance of galvanic cells in electrochemistry?
Galvanic cells are pivotal in understanding electron flow, reaction spontaneity, anode, and cathode.
How is mass spectrometry used in chemistry?
It is used to determine the atomic mass and abundance of isotopes.
How can PES graphs help in understanding electron configurations?
PES graphs can be interpreted to deduce electron configurations.
Explain the concept of isoelectronic species in terms of ionic radii.
Isoelectronic species have the same number of electrons but different nuclear charges, impacting ionic radii.
Describe the calculation involving Gibbs free energy.
Gibbs free energy is calculated to determine the spontaneity of a reaction.
Explain the concept of hybridization in relation to molecular geometry.
Hybridization is important in understanding the geometry and properties of molecules.
What is the purpose of VSEPR theory in chemistry?
VSEPR theory is used to determine molecular shapes and angles.
