An attraction between two atoms, molecules or ions is termed as a chemical bond. Due to the presence of a chemical bond, a chemical compound is formed. A chemical bond can be formed due to the sharing of electrons, as in covalent bond, or can be formed due to attraction between oppositely charged ions, as in ionic bond.
