The possible value of `l` and `m` for the last electron in the `Cl^(- )ion` are :

A

`1 and 2`

B

`2 and + 1`

C

`3 and -1`

D

`1 and -1`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) `Cl_17^(-) : [Ne] 3s^2 3 p^6`
Last electron enters `3p` orbital.
`:. l = 1 and m = 1, 0, - 1`.
