Ordinary atoms that possibly attain or reduce electrons are termed ions. If a neutral atom loses an electron, it will become a beneficial ion. If it gains an electron, it will become a adverse ion. These simple subatomic particles—protons, neutrons, and electrons—are on their own made up of lesser substances, for instance quarks and leptons.
