How can we find the valency of aluminium?

How can we find the valency of aluminium?

Atomic number of aluminium is 13 so its electronic configuration is 2, 8, 3. Since it has 3 electrons in its valence shell, it will lose 3 electrons to complete its octet hence its valency is +3.

Is 3 the valency of aluminium?

Valency of aluminium is: Atomic number of aluminium is 13 so its electronic configuration is 2, 8, 3. Since it has 3 electrons in its valence shell, it will lose 3 electrons to complete its octet hence its valency is +3.

What is the valence and valency of aluminium?
