What are the four sets of quantum numbers for nickel?

The quantum numbers for the last valence electron in nickel are (3, 2, 0, - ½).

The electron configuration of nickel is [Ar]4s²3d⁸

The last electron added is a 3d electron, so n = 3 and l = 2.

We construct a table of quantum numbers.

Element n l mₗ mₛ

Sc 3 2 2 + ½

Ti 3 2 1 + ½

V 3 2 0 + ½

Cr 3 2 - 1 + ½

Mn 3 2 - 2 + ½

Fe 3 2 2 - ½

Co 3 2 1 - ½

Ni 3 2 0 - ½

The quantum numbers for the last electron in nickel are (3, 2, 0, - ½).
