- ATrue
- BFalse
2Protons and electrons are roughly the same size

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