Solution

The correct option is B 4
Valency of carbon in $C O_{3}^{2 -}$ ion
Let the valency of carbon be $x$
$∴ C O_{3} = - 2$ [Overall charge is $- 2$ ]
$∴ x + 3 \times (- 2) = - 2$ [Charge on oxygen atom is $- 2$ ]
$∴ x - 6 = - 2$ $↓$
$∴ x = - 2 + 6$ [Electrons per shell of oxygen $⟶ 2, 6$ ]
$∴ x = + 4$ It gains $2$ electrons from other atom to complete octet. Hence, has $- 2$ valency.
Valency of Carbon in $C O_{3}^{2 -}$ is $4$ .
