Question

Which of the following set of quantum number is not possible?
(A) n=3, l=2, m=-1, s=-1/2
(B) n=4, l=2, m=-2, s=+1/2
(C) n=3, l=1, m=2, s=-1/2
(D) n=4, l=1, m=1, s=+1/2 ​

Answer 1

Answer:

(a)& (b) are not possible because, n=1, then l=0 to (n-1)

so if n=1, then l=0

if l=0, then m=-l to +l including zero, if l=0, m¹1
