Question

What are the conditions necessary for the formation of covalent molecules?

Answer in Brief

Solution 1

Covalent bond is formed when the participating atoms contribute one electron each to form an electron pair which is then shared by the participating atoms in such a manner that each atom attains the nearest noble gas configuration. 

Each atom should not be completely filled before covenant bond formation.
