What is electronic polarization?

Electronic polarization refers to the distortion of the electron cloud around atoms or molecules when an external electric field is applied. This distortion occurs because the electrons are displaced in response to the field, creating a dipole moment even in non-polar substances. As a result, the material can exhibit a polarization effect, which influences its electric properties and behavior in the presence of electric fields. This phenomenon is essential in understanding dielectric materials and their applications in capacitors and insulators.
