In an atom, the total number of electrons having quantum number `n = 4, |m_(l)| = 1` and `m_(s) = - (1)/(2)` is

A

6

B

12

C

20

D

18

Verified by Experts

The correct Answer is:

B

`|m_(l)| = 1` means `m_(l)` can be +1 and -1 so for n = 4, six orbitals are possible and can hold 12 electrons.
