Direction in anions increase in polarizability

Postby 205192823 » Tue Nov 19, 2019 6:56 pm

Which way do anions increase in polarizability? is it left and up the periodic table like cations or are they different?

Anions are more polarizable since they have more electrons and therefore are easier to induce a dipole in

Anions that have the greatest polarizability are those that are large and less electronegative. Cations that have greater polarization power are those that are smaller and have a high charge.

The trend for increasing polarizing power for cations would be decreasing size and increasing charge, which is why Al+3 is a common example for a cation with very strong polarizing power. On the other hand, the trend for anions would be increasing polarizability moving down and to the right.
