The correct set of quantum numbers for the unpaired electron of chlorine atom is

Options

A. `{:(n,l,m),(2,1,0):}`
B. `{:(n,l,m),(2,1,1):}`
C. `{:(n,l,m),(3,1,1):}`
D. `{:(n,l,m),(3,0,0):}`

Answer

C

Explanation

Electronic configuration of Cl is
[Ne] `3s^2 3p^5 ` or [Ne]
So for the unpaired electron `(3p_z^1)`
n = 3,l = 1, m = 1, `s=+ 1/2`
