Solution
Valency:
The capacity with which an atom of an element combines chemically with the atom(s) of another element is called the combining capacity or valency of the element.
Valence electron:
Electrons in the outer shells that are not filled are called valence electrons.
Valence is the number of electrons an atom must lose or gain to attain the nearest noble gas or inert gas electronic configuration.
The valency of an atom:
It is described by the total number of electrons lost, gained, or shared to complete its octet.
Valency of is, As it loses valence electron for the bond formation.
Valency of is, As it loses valence electron for the bond formation.
Valency of is, As it loses valence electron for the bond formation.
Valency of is, As it gains electron in its valence shell for the bond formation.
Valency of is, As it gains electron in its valence shell for the bond formation.
Valency of is, As it gains electron in its valence shell for the bond formation.
