List a possible set of four quantum numbers (n, l, ml, ms) in order, for the highest energy electron in gallium?

Gallum: Z = 31

electron configuration: [Ar] 4s^2 3d10 4s2 4p1

Highest energy electron: 4p1

Quantum numbers:

n = 4, because it is the shell number

l = 1, it corresponds to type p orbital

ml = may be - 1, or 0, or + 1, depending on space orientation, they correspond to px, py, pz

ms = may be - 1/2 or + 1/2, this is the spin number.
