If an electron has spin quantum number of `-(1)/(2) ` and magnetic quantum number of -1 it cannot be present in:

Options

A. d-orbital
B. f-orbital
C. p-orbital
D. s-orbital.

Answer

D

Explanation

As m = (2l + 1), hence m = - 1 means, - 1 = 2l + 1 l = 1 (magnitude).
i.e., least value of l = 1 . So it cannot be present in s - orbital. Because for s oribital l = 0 .
