Which of the following is not permissible arrangement of electrons in an atom ?

Options

A. `n = 3, l = 2,m = -2, s = -1//2`
B. `n = 4, l = 0, m = 0, s = - 1//2`
C. `n = 5, l = 3, m = 0, s = + 1//2`
D. `n = 3, l = 2, m = -3, s = - 1//2`

Answer

D

Explanation

(d) If `n = 3`
`l = 0 "to" (3 - 1) = 0, 1, 2`
`m = -1 "to" + 1 = -2, -1, 0, + 1, + 2`
`s = +- (1)/(2)`.
`:.` Option (d) is not a permissible set of quantum number.
