Question

In the molecular formula of AICL³ write the valency of aluminum and chlorine

Answer 1

Valency of aluminum=3
Valency of chlorine=1

Answer 2

Helloo!!

Molecular Formula of aluminum chloride is AlCL3

Configuration of Aluminium is 2,8,3
& Configuration of chlorine is 2, 8, 7

hence, aluminum has 3 valance Electrons in outermost shell!

and valency of chlorine is -1 as it requires 1 electrons to complete it octet!

hope it helps
