Here are the rules. If you don't know them you should.
n = 1,2,3,4, etc..........
l = 0,1,2, etc up to n-1
ml = -l in increments of 1 to 0 and up to +l; i.e., for l = 2 then ml can be -2,-1,0 ,+1, +2
ms = only +1/2 or -1/2
Here are your first 3 answers which I will call A,B,C.
A. 2, -3, 1/2
B -3, 2, 2, -1/2
C 5, 2, 1, -1/2
A can't be correct because l can't be negative.
B can't be right because n can't be negative.
C is possible. The rules (read them) allow these numbers.
You do the others.
Which of the following set of quantum numbers (ordered n, ℓ, mℓ, ms) are possible for an electron in an atom?
Check all that apply.
2, -3, 1/2
-3, 2, 2, -1/2
5, 2, 1, -1/2
3, 2, 2, -1/2
4, 3, 4, -1/2
3, 2, 1, -1
4, 3, -2, 1/2
3, 3, 1, -1/2
