Question

What's the valency of an element having 3 valence electrons in its outermost, M, shell?​

Answer 1

Answer:

as valency = valence electrons in outermost shell

so valency of element would be 3

Answer 2

Answer:

+3

Explanation:

valency can be found by group no. in periodic table...

suppose Aluminium (Al) has atmic no. 13

it'll have k= 2

L=8

M=3

So by losing its 3 valance electrons,it'll complete its octet
