Which of the following species has four lone..

A

`I`

B

`O^-`

C

`Cl^(-)`

D

`He`

Text Solution

Verified by Experts

The correct Answer is:
C
Outer electronic configuration of Cl atom
`= 3s^(2)3p_(x)^(2)p_(y)^(2)p_(z)^(1)`
Outer electronic configuration of `Cl^(-) ion = 3s^(2)3p_(x)^(2)p_(y)^(2)p_(z)^(2)`
Hence `Cl^(-)` has 4 unshared pair of electrons.
