What exactly is polarizability?

Polarizability refers to how easily an atom’s electrons can be distorted by polarizing atoms. The lower the electronegativity, the higher the polarizability, because the atom’s electrons are not held as tightly. Likewise, the larger the atom, the higher the polarizability.

usually highly polarizable atoms/molecules have big electron clouds (so anions, large atoms/molecules with lots of electrons are highly polarizable)

Polarizability is how easily the electron cloud of an atom (usually a large anion) is distorted by another atom (usually a small highly charged cation). The atom causing the distortion (the cation) has polarizing power, which increases as the atom becomes smaller and more highly charged. The atom that is being distorted (the anion) is polarized.
