Question

Write the valencies of the following elements.

(a) Phosphate

(b) Zincate

(c) Biphosphate

(d) Silicate

Answer 1

Valency -

• The combining capacity of an element during the formation of a molecule or compound is known as its valency.
• Different atoms have different combining capacities.

The valencies of the following elements.

(a) Phosphate $\left({{\mathrm{PO}}_4}^{-3}\right)$ - Trivalent

(b) Zincate $({{\mathrm{ZnO}}_2}^{-2})$ - Divalent

(c) Biphosphate $\left({\mathrm{HPO}}_4^{-2}\right)$ - Divalent

(d) Silicate $\left({\mathrm{SiO}}_3^{-2}\right)$ - Divalent
