How can you tell if something is polarizable?

"Something that is highly polarizable means that it is susceptible to being distorted causing a dipole to form. A larger atom is more polarizable than a smaller one because its outer electrons are less tightly bound and its electron cloud is more likely to be distorted by, say, a cation."

^ Chem_Mod said that in another post when someone asked about polarizability.

In addition to larger atoms having more polarizability, atoms with less electronegativity are more polarizable because atoms with larger electronegativities want more electrons and so they hold onto their electrons more tightly. Thus, when categorizing atoms in increased polarizability, you first look at size (bigger=more polarizable) and then electronegativity (less electronegative=more polarizable) when the atoms are in the same row.
