Explanation:
Polarizability is a measure of how easily an electron cloud is distorted by an electric field.
Typically the electron cloud will belong to an atom or molecule or ion.
The electric field could be caused, for example, by an electrode or a nearby cation or anion.
If an electron cloud is easy to distort, we say that the species it belongs to is polarizable.
Polarizability, which is represented by the Greek letter alpha, α, is experimentally measured as the ratio of induced dipole moment p to the electric field E that induces it:
α = p/E
The units of α are C m2 V-1.
