likely charge of atoms

so I understand that atoms want to reach an octet so s-block atoms will likely form +1 or +2 ions and groups 15-17 will likely form -1, -2, or -3 ions. But what about gallium (Ga) which would need a -5 charge to reach the next noble gas? would it just become +1 to reach a complete 3d orbital?
basically, what's the likely charge of Ga or any group 13 (and 14) element ?

I think Ga would likely be 3+ because it has 3 valence electrons.

Because Gallium is a metal, it is more likely to form a cation by removing three of its electron in order to obtain the nearest full shell. Since it has three valence electrons (its configuration is [Ar] 3d10 4s2 4p1) Gallium's cation would be Ga3+.
