Number of valence electrons in chlorine ion are:

a) 16

b) 8

c) 17

d) 18

$\large\star{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}\star$

Option b)8 is the correct answer.

$\large\bold\color{orange}{Explanation}$

The electronic configuration of chlorine is 2, 8, 7 (Atomic number-17).

Clorine Ion (Cl⁻) is formed from adding one electron so the new electronic configuration is 2, 8, 8. So the valence electrons is 8.

Answer 2

The electronic configuration of chlorine is 2,8,7 (Atomic number-17)

Cl-ion is formed from adding one electron so new electron is 2,8,8 so valance electron is 8
