Because you always want the lowest formal charge possible in order to have the most stable Lewis Structure. I heard from my TA that it is possible you will have to calculate formal charges for points on either Test 3 or the final.

It means they have the same number of electrons. Ions of one element may be isoelectronic with uncharged atoms of another due to the gain/loss of electrons.

The mass of leftover reactant is just the mass of the non-limiting reactant that remains when the limiting reactant has been used up.

Jumping down 2 levels (from n=5 to n=3) is a larger jump distance, which creates a lower wavelength and thus higher energy as far as I know.
A lower wavelength means the frequency is higher because there are more waves in the same amount of time. So, because the frequency of gamma rays is the highest, their energy will also be the highest.

My TA told me not to worry about memorizing the electromagnetic spectrum. I would just focus on remembering the relationships between energy, frequency, and wavelength.
