Fajan gives the following four rules for thePolarization

Polarization will be increased by:
1. High charge and small size of the cation.

2. High charge and large sizeof the anion.

3. The polarizability of an anion is related to the deformability of its electron cloud (i.e. its “softness”)

4. An incomplete valence shell electron configuration. Noble gas configuration of the cation produces better shielding and less polarizing power.

Thank You
