Question

if Z = 3 what would be the valency of the element also name the element
answer in better way

Answer 1

The electronic configuration of (Z) = 1S^2 2S^1

Thus, outermost shell has 1 electron.

So, its valency =1

Atomic number (Z) = 3, So name of element is lithium.

Answer 2

Hello mate

The element is Lithium (Li).

The valency is 1. ( Li ₃ = 1s² 2s¹)

It can readily loss one electron from 2s to attain a stable doublet configuration.

Please do me a favor and mark me the brainliest.
