Chemical Bond 

A chemical bond is the attraction between atoms and molecules that allows the formation of polyatomic compounds. It occurs due to electromagnetic force of attraction between ions of opposite charges.

Atoms react together to form chemical bonds because they have a tendency to complete their outermost shell electrons to gain stable noble gas like electronic configuration,

Types of chemical bonds:

(1) Intramolecular bond :

(i)            Ionic bond

(ii)           Covalent bond

(iii)          Coordinate covalent bond / dative bond

(iv)          Metallic bond

(2)          Intermolecular bond :

(i)           Hydrogen bond

(ii)          Dipole-dipole interactions

(iii)          London dispersion forces (Van der Waals force)
