Re: Anions
No, because the first two rows of the periodic table are metal cations, and therefore have polarizing power. So, not all metals are good candidates for polarizability!
Re: Anions
Anions are polarizable (exhibiting distortion) whereas cations have polarizing power (distorting anions).

Re: Anions
Cations will always be the type of ions that will possess polarizing power whereas anions will possess polarizability.

Re: Anions
Polarizability depends on size and charge. No assumptions can be made since each element has a different amount of electrons. The more electrons the farther they are away which allows the nucleus to not have a strong hold on them. Thus, the more electrons the easier it is to have a dipole moment because of the loose electrons.

Re: Anions
In the textbook it states that, "When a small, highly charged cation is close to a large anion, the electron cloud of the anion is distorted in the process we call polarization." This implies that the anion is polarizable while the cation should have the polarizing power. Smaller atoms with a higher positive charge have a greater polarizing power while larger anions have greater polarizability.
