Atoms are composed of electrons, protons and neutrons whose relative masses and charges are shown in Table 2.1. The atomic number is the number of protons in the nucleus and gives the atom its identity. C has 6 protons, for example. For a neutral atom the number of electrons must equal the number of protons. Ions have unequal numbers of protons and electrons and may have either positive ( cation ) or negative ( anion ) net charges. Neutrons add mass but no charge – the mass number is the sum of the number of protons and neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons. The elements are given symbols,
