What happens when an electron gets "excited?"
It jumps from the ground state to the excited state, then returns to the ground state, emits its energy as a photon.

Why do we look to the noble gases when determining most likely charge?
They have a full shell which makes them the most stable!
400
Why does Ca2+ have a smaller atomic radius than Ca?
(1) It lost an energy level
(2) Less shielding because the remaining electrons are closer to the nucleus
