Types of Chemical Bond

Fajans' rule states that a compound with low positive charge, large cation and small anion has covalent bond where as a compound with high positive charge, small cation and large anion are ionic bonded.

The bond formed by electrostatic attraction between positive and negative ions is called ionic bond.

List the different types of chemical bonds.
