Solution

Valency:
The combining capacity of the atom of an element to complete its octet is called its valency.
It is always a whole number.
Valency varies from 1 to 8.
Valency is always positive.
An element with a valency one called monovalent, with two called divalent, with three called trivalent.
Therefore, elements with a valency equal to 3 are called trivalent.
