i|on «Y uhn, -on», noun.1. an atom or a group of atoms having a negative or positive electric charge as a result of having lost or gained one or more electrons. When an acid, base, or salt dissolves in water, some of its molecules separate into positive and negative ions. Each molecule forms two or more ions whose electric charges neutralize each other when the ions are recombined into a molecule. Cations are positive ions formed by the loss of electrons and move toward the cathode; anions are negative ions formed by the gain of electrons and move toward the anode. The number of electrons lost or gained is denoted by a plus sign (for positive ions), as in Na+ or Mg2+, or a minus sign (for negative ions), as in Cl― or S2―.2. an electrically charged particle formed in a gas, as by the action of X rays or an electric current.╂[< Greek ión, neuter present participle of iénai to go]-ion,suffix added to verbs to form nouns.1. act or process of _____ing: »Attraction
