Question

The correct set of quantum numbers for the unpaired electron of chlorine atom is
A. `{:(n,l,M),(2,1,0):}`
B. `{:(n,l,M),(2,1,1):}`
C. `{:(n,l,M),(3,1,0):}`
D. `{:(n,l,M),(3,0,0):}`

Answer 1

Correct Answer - C
Electronic configuration of Cl is

So for the unpaired electrons `(3p_z^1)` : n=3, l=1, m=1 , `S=+1/2`
