Explanation:
Ans: Covalency: The number of electrons that an atom can shared to get stable electronic configuration is called it covalency.
Ex: In order to get stable Neon gas configuration Carbon shares its four valence electrons. Thus its covalency is 4.
Electrovalency:
The number of electrons lost or gained by an atom to get stable electronic configuration in forming ionic bond is called its electrovalency.
Ex: In getting Neon gas configuration Sodium (Na) loses one electron to Chlorine.
Thus electrovalency of Sodium is 1.
