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

Answer»

`2,0,0 + (1)/(2)`
`2,1,-1 + (1)/(2)`
`3,1,1, pm (1)/(2)`
`3,0,0 pm (1)/(2)`

SOLUTION :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`
