Question

what is the valency of aluminium and nitrate in al(no3)3

Answer 1

Answer:

+3 is the valency

Explanation:

if like this give me thumbs up

Answer 2

VALENCY -

• The number of electrons present in the outermost shell of an atom.
• It represents the combining power of an element.
• In the given compound aluminium nitrate,

The valency of aluminum - +3

The valency of nitrate ion is -1.

• So, three nitrate ions need to be attached to the aluminium to form a stable compound.
• Three electrons from nitrate ions will be shared with the aluminium to complete its electronic configuration.
