You are probably thinking what about group 4?
The answer is that because it only fills half of its outer shell it has the option to
gain or lose electrons therefore we cannot say for sure.
Group 8/0 has no charge this is because it has a full outer shell of electrons and
therefore doesn't need to gain or lose electrons.
I hope this answers all of your questions about ionic charges if it doesn't start a
discussion with GEORGIA IONIC CHARGES and I will answer!
