Which set of quantum number is not consistent with the quatum mechanical theory.

Options

A. `n = 2, l = 1, m = 1, s = 1//2`
B. `n = 4, l = 3, m = 2, s = - 1//2`
C. `n = 3, l = 2, m = 3, s = + 1//2`
D. `n = 4, l = 3, m = 3, s = + 1//2`

Answer

C

Explanation

( c) There is a well-defined co-relation between `n, 1 m` and `s` quantum numbers in an atom. If `n = n` then `1 = (n - 1), m`
will be `+- 1` and `s` will always be `+- 1//2`. For `n = 3` there cannot be `m = 3`. Highest value `m` will be `2`.
