Question

Which of the following sets of quantum numbers are not allowable and
why ?

(a) n=3, 1=2, m = +1, s = 0
(b) n=2, 1=2, m=-1, s= +1/2
(c) n=2, 1=1, m=0, s= + 2​

Answer 1

Answer:

All three are not allowed.

Explanation:

a) s = 0; which is not possible.

b) for n=2 ; l must be 1. but here l = 2.

c) s can have values ½ or ‐½.

Answer 2

Explanation:

allowable and permitable because is this house x

(a) n=3, 1=2, m = +1, s = 0

(b) n=2, 1=2, m=-1, s= +1/2

(c) n=2, 1=1, m=0, s= + 2====mc²2222
