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

A

3

B

5

C

6

D

9

Text Solution

Verified by Experts

The correct Answer is:
C
`{:(4 s,4p,4 d,4 f,),(m = 0,m = +- 1"," 0,+- 2"," +- 1"," 0,+-3"," +-2"," +-1"," 0,):}`
Thus total 6 orbitals having 6 electrons with `S = - (1)/(2)`
