What is a chemical bond ?

A chemical bond may be defined as the chemical force that keeps all the atoms in any molecule together. The combining atoms acquire stable electronic configuration either of the following three ways.

A chemical bond may be defined as the chemical force that keeps all the atoms in any molecule together.

The combining atoms acquire stable electronic configuration either of the following three ways.

(i) By the transfer of electrons from the atom of an element to atom of another. This gives rise to an ionic (electrovalent) bond.

(ii) By mutual sharing of the electrons. This gives rise to a covalent bond.

(iii) By one-sided sharing of the electrons. This gives rise to a coordinate bond. This bond is also called as dative bond.

(iv) Formation of the various types of bonds is described below.
