Well, I'm assuming we're talking the most commonly used charges of these elements...

AlCl2 should actually be AlCl3. That's because aluminum has a charge of +3, and Cl has a charge of -1, so the formula should balance these charges out, hence AlCl3.
Same with NaO. Na+1 + O-2 = Na2O
Mg+2 + P-3 = Mg3P2
Ca+2 + I-1 = CaI2
Li+1 + N-3 = Li3N
K+1 + S-2 = K2S
Hope that helps.

Everyone is wrong:

AlCl3
Na2O
Mg3P2
CaI2
Li3N
K2S

are the right formulas

Its not AlCl2, its Al2Cl3

It shud be Na2O

It shud be Mg3P2

It shud be CaI2

It shud be Li3N

It shud be K4S2
