Polarizability

Postby Angela Grant 1D » Thu Nov 08, 2018 6:22 pm

Can someone explain the relationship between number of electrons and polarizability?

Polarizability increases with the increase in number of electrons. This is due to the decreased control that the nuclear charge has on the overall charge distribution in the atom. In small atoms, the electron cloud is small and dense, and the electrons have a stronger interaction/attraction with the positively charged nucleus. In large atoms, there is less of an attraction that allows the electrons to be more fluid, thus making it easier to distort the electron cloud and increasing polarizability.

The greater the number of electrons, the less control the positive nuclear charge exerts on the electrons due to shielding, thus causing the larger electron cloud to distort more and increasing polarizability.

Polarizability gets higher as the number of electrons increases. This is because the nuclear charge has less control over the electrons due to the shielding effect. Therefore, the outer electrons are more easily distorted.
