2.Covalency
In the formation of a covalent compound (or molecular compound),the number of electrons shared by one atom of an element to achieve the nearest inert gas electron configuration is known as its covalency.If an atom shares 1 electron, its covalency will be 1, if it shares 2 electrons,then its valency will be 2,and so on.This point will become more clear from the following examples.
