Ion

Ion (chemistry), particle formed when a neutral atom or group of atoms gains or loses one or more electrons. An atom that loses an electron forms a positively charged ion, called a cation; an atom that gains an electron forms a negatively charged ion, called an anion. Atoms can be converted to ions by radiation such as X rays or light of sufficient energy. This kind of radiation is thus called ionizing radiation. See Ionization.
