17.7 Microscopic models of electric polarisation

 

This section from  starts from a description of a .

The figures show a large scale view of an atom. Figure a shows an unpolarized atom, with protons and neutrons in the center and a circular electron cloud surrounding the nucleus. Figure b shows a polarized atom and positive and negative external charges. The atom is oblong in shape with the electron cloud being pulled towards the positive external charge, and the nucleus being pulled towards the negative external charge. Figure c shows another oblong polarized atom.
