What is the ground state electron configuration of Ga^3+?

Could someone please advise?

[Ar] 3d10

basically Ga Z=31
but it's Ga3+ so 31-3=28

Ga^3+: [Ar]3d10
1. Take Gallium's electron configuration [Ar]3d10 4s2 4p1
2. Remove 3 electrons (remove 4s2 4p1)

For trickier problems, I like to write out the neutral atom's electron configuration first, putting all the orbitals in their proper order by the amount of energy they have. Then, to form ions, specifically anions, I would remove the specified number starting from the outermost, highest-energy electrons.
