Question

Name two tetravalent cations with their formulae and valencies.

Answer 1

Tetravalent cations:

1. The cations with a $+4$ charge as their valency are known as tetravalent cations.
2. Such atoms lose four electrons from their valence shell and attain a $+4$ charge.

The tetravalent cations are carbon $\left(\mathrm{C}\right)$ and silicon $\left(\mathrm{Si}\right)$, having a chemical formula, ${\mathrm{C}}^{4+}\mathrm{and}{\mathrm{Si}}^{4+}$respectively. The valency of both the cations is $+4$.
