The definition of atomic mass
The mass of an atom (protons and neutrons)
Explain why atomic radius decreases as you move across periods AND why it increases as you move down groups
Multiple answers will work...
Across: more protons create a stronger pull. Electrons are brought in closer to the center, creating a smaller radius
Down: more electron energy levels. More shielding. Effect of protons on electrons is less strong
The definition of Ionization energy
The amount of energy it takes to remove one electron from an atom
