ion meaning

EN[ˈaɪən] [ˈaɪɒn] [ˈaɪ.ɑn] [-aɪən]
  • An ion (/ˈaɪən, -ɒn/) is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge.
  • Ions can be created, by either chemical or physical means, via ionization. In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation.
  • In the case of physical ionization of a medium, such as a gas, what are known as "ion pairs" are created by ion impact, and each pair consists of a free electron and a positive ion.
