Polarizing Power vs Polarisabiltiy

Postby sallina_yehdego 2E » Tue Nov 06, 2018 10:25 pm

What's the difference between polarizing power and polarisability?

The ability of a cation to distort an anion is known as its polarization power. Smaller, more positive cations pull electrons more strongly so these cations are said to have a strong polarization power.
Polarizability is essentially the ability of the anion to pull in those electrons. Smaller negative charges and larger anion sizes tend to have a greater polarizability than anions with small size and a greater negative charge.

It helps to remember that polarizability is larger and inversely related to electronegativity and positive charge, and that polarizing power is smaller and directly related to electronegativity and positive charge.
