Question

valency of zinc in zinc oxide

Answer 1

In Chemistry, valence of an element refers to the combining power of an element’s atoms with other elements to form compounds.

The valence of zinc in zinc oxide is +2. Thus in another way it can be said that Zinc has the capacity to donate two electrons to oxygen and oxygen on gaining 2 electrons from it forms the compound zinc oxide.

Answer 2

Valency of zinc in zinc oxide is +2

Zinc oxide = ZnO

Zn O

1 1

Oxygen's valency is always 2.

So multiply it with 2

Zn O

1×2 1×2

Valency of Zinc = 2

Valency of oxygen = 2
