Question

The number of electrons in outermost shell is 5. What is its valency and give reason to it.

Answer 1

it have 3 valence electron....... so its valency is 3

Answer 2

the valency is (8-5)=3
because it is easy for that element to gain three element rather than loosing all 5. so it's valency is 3.

it can also show valency 5 but that's for higher classes.

hope it helps.
