Question

THE OXIDE OF ALUMINIUM HAS A CHEMICAL FORMULA Al2O3. STATE THE VALENCY OF ALUMINIUM

Answer 1

Al has a valence of 3 and it is denotes and oxygen has a valency of 2.

It usually gives positive ions that have made with negative ions from the oxygen and forms a stable approach.

This usually gives better approaches and includes ionic compounds and valence of AI is 3 and O is 2.

Answer 2

Hi,

Here is your answer,

Aluminium has a valence of 3

Therefore it gradually denotes and O₂ with the valance electron 2

Hope it helps you !
