Definitions of ion

  1. a particle that is electrically charged ( positive or negative); an atom or molecule or group that has lost or gained one or more electrons
  2. One of the elements which appear at the respective poles when a body is subjected to electro- chemical decomposition. Cf. Anion, Cation.
  3. One of the small electrified particles into which the molecules of a gas are broken up under the action of the electric current, of ultraviolet and certain other rays, and of high temperatures. To the properties and behavior of ions the phenomena of the electric discharge through rarefied gases and many other important effects are ascribed. At low pressures the negative ions appear to be electrons; the positive ions, atoms minus an electron. At ordinary pressures each ion seems to include also a number of attached molecules. Ions may be formed in a gas in various ways.
  4. One of the electrified particles into which a gas, or a substance in solution, is broken up under the action of electricity.
  5. A group of atoms or parts of molecules carrying a charge of electricity and constituting one of the elements of an electrolyte. The ions charged with negative electricity which are evolved at the positive pole ( anode) are called anions; those charged with positive electricity, at the negative pole ( cathode), cations.
  6. One of the elements which appear at the poles, when a body is subjected to electro- chemical decomposition.
  7. Any one of the elements which are evolved out of a particular substance by the voltaic current, and which appear at the poles of the battery.
