4The neutrons and protons of a nucleus are tightly bound together by the shells of an atom.

5Since the electrons move very fast around the nucleus, the moving electrons form a sort of fuzzy sphere or shell around the nucleus - which is referred to as the 'electron cloud'. The electrons move around in regions called electron shells.
