A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

The bond formed by the sharing of single pair of electrons between the atoms is known as covalent bond.

Covalent bond is name given to the chemical bond, which is formed by the sharing of single pair of electrons between the two atoms.

  • The electrons pairs shared between the two atoms are known as shared pairs, and due to these shared pairs the covalent bonds are the stable bonds which require huge energy to break.
  • Covalent bonding is possible only with the elements having the higher ionisation energy. This is because, atoms having higher ionisation energy restricts the acceptability of further electrons.
  • For example - When two hydrogen atoms (H) shares one electrons from their respective s-subshell, they attain a stable configurable of noble element (helium). Hence, they form [tex]H_{2}[/tex] gas, with a strong covalent bond.

Thus, we can conclude that the covalent bond is a bond in which a single pair of electrons is shared between a pair of atoms.
