Detailed explanation-1: -A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Detailed explanation-2: -The bond formed when atoms share electrons is called a covalent bond. (Unlike ionic bonds, which involve the complete transfer of electrons). A group of atoms held together by covalent bonds is called a molecule.

Detailed explanation-3: -Covalent bond. The bond formed by sharing of one, two or three pairs of electrons between two atoms is known as covalent bond.
