Which set of quantum number is not possible for electron un `3^(rd)` shell ?

Options

A. `n = 3 l = 2 m = -1 s = + 1//2`
B. `n = 3 l = 2 m = -1 s = - 1//2`
C. `n = 3 l = 2 m = 0 s = + 1//2`
D. `n = 3 l = 3 m = 0 s = - 1//2`

Answer

D

Explanation

(d) Value of `1` are given by `0` to `n - 1`. For an electron in `n = 3`. Value of `1` can be `0, 1` or `2`.
