Answer 2

Answer:

valency of an element is its combining capacity

it is the number of electrons it can lose, share or gain to become stable ( i.e. to attain octet- duplet for hydrogen )

Explanation:

elements having 1,2 or 3 valence electrons lose these to become stable and hence have valency 1,2 or 3 respectively. they are metals.

elements having 4, 5, 6, or 7 valence electrons share or gain 4, 3, 2, or 1 electron respectively to become stable and hence have valency 4, 3, 2 or 1 respectively. they are non metals or metalloids
