Types of Valency
There are two types of valency : Electrovalency and Covalency.If an element combines by the loss or gain of electrons to form electrovalent compounds (or ionic compounds),its valency is known as electrovalency,and if an element combines by the sharing of electrons to form covalent compounds (or molecular compounds), its valency is known as covalency. We will now discuss these two types of valency in detail. Let us take the case of electrovalency first.
