i•on

(ˈaɪ ən, ˈaɪ ɒn)

n.
1. an atom or atom group electrically charged by the loss or gain of electrons, represented by a plus or a minus sign, as a cation (Na + , Ca + + ) or anion (Cl).
2. one of the electrically charged particles formed in a gas by electric discharge.

i·on

(ī′ən, ī′ŏn′)
An atom or a group of atoms that has an electric charge. Positive ions, or cations, are formed by the loss of electrons; negative ions, or anions, are formed by the gain of electrons. See Note at charge.
