The nucleus is a solid core, and that core is covered by shells of electrons.Just as the outside layer of an onion is the only one that goes brown, so it is only the outer shell of an atom that reacts with other atoms.It makes sense then that we need to know how many electrons fit into each onion like shell surrounding the nucleus. It is important to realise that this only applies for the first 20 elements; after this things become more complex.
