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

Options

A. `2,0,0 + (1)/(2)`
B. `2,1,-1 + (1)/(2)`
C. `3,1,1, pm (1)/(2)`
D. `3,0,0 pm (1)/(2)`

Answer

C

Explanation

The electronic configuration of CI would be `rarr 1S^2,2S^2 2P^6,3S^2 3P^5`
The p-orbital has 1 unpaired electron and the quantum number corresponding to it as

`n=3,1=1 , m =1,s=1//2`
