What is Polarizing power?

The ability of a cation to distort an anion is known as its polarization power and the tendency of the anion to become polarized by the cation is known as its polarizability.
The polarizing power and polarizability that enhances the formation of covalent bonds is favored by the following factors:
Small cation: the high polarizing power stems from the greater concentration of positive charge on a small area. This explains why Lithium Bromide is more covalent than Potassium Bromide (Li+ 90 pm cf. K+ 152 pm).
Large anion: the high polarizability stems from the larger size where the outer electrons are more loosely held and can be more easily distorted by the cation. This explains why for the common halides, iodides, are the most covalent in nature (I- 206 pm).
Large charges: as the charge on an ion increases, the electrostatic attractions of the cation for the outer electrons of the anion increases, resulting in the degree of covalent bond formation increasing.
