Number of valence electrons in `Cl^(– )` ion are:

A

16

B

8

C

17

D

18

Text Solution

Verified by Experts

The correct Answer is:
B
Electronic configuration of Cl(Z = 17) = 2, 8, 7. Thus, it has 7 valence electrons. `Cl^(-)` gains 1 electron to form Clo ion. So, number of valence electrons = 7+ 1 = 8.
