Question : 30
Total: 67
Explain, giving reasons, which of the following sets of quantum numbers are not possible.
(a) n = 0, l = 0,m l m s
(b) n = 1, l = 0,m l
(c) n = 1, l = 1,m l m s
(d) n = 2, l = 1,m l
(e) n = 3, l = 3,m l m s
(f) n = 3, l = 1,m l
(a) n = 0, l = 0,
(b) n = 1, l = 0,
(c) n = 1, l = 1,
(d) n = 2, l = 1,
(e) n = 3, l = 3,
(f) n = 3, l = 1,
Solution:
(a) Not possible because n ≠ 0
(c) Not possible because when n = 1, l = 0
(e) Not possible because when n = 3, l = 0, 1, 2, and not equal to 3.
(c) Not possible because when n = 1, l = 0
(e) Not possible because when n = 3, l = 0, 1, 2, and not equal to 3.
