What is the difference between polarizing power and polarizability?

Polarizing power = cation's ability to distort electron region of anion
Polarizability = anion's tendency to be distorted

Generally atoms with polarizing power have small atomic radii and are partial negative. Atoms that are polarizable have large atomic radii and are partial positive.

Polarizing power describes the behavior of a cation pulling, or distorting, the electrons from an anion.
Polarizability describes the behavior of a anion's electrons being pulled towards the cation.

Typically, anions are polarized and cations are the polarizing power. Polarizability follow the trend of atomic radius. When you increase the size, you increase the polarizable properties.

polarizing power is how powerful a specific ion can polarize another ion (pull/distort a electron cloud towards it)

polarizability is how much a ion can be polarized (how distorted it can become)
