Definition of polarizability in English English dictionary
The relative tendency of a system of electric charges to become polarized in the presence of an external electric field
A measure of the degree to which any given atom or ion undergoes polarization in the presence of an external electric field
{i} ability to be polarized, ability to be divided into two distinct poles; ability to be divided into two factions (also polarisability)
Relates the induced electric dipole moment, p, of an atom or molecule to the local electric field it experiences as a = p / Elocal, hence depending on the displacement by the field of the electronic charge from its equilibrium position in the atom or molecule
of orbitals means that the electron cloud can be shifted towards a positive charge or away from a negative charge due to electrostatic attraction and repulsion
