a particle that is electrically charged (positive or negative); an atom or molecule or group that has lost or gained one or more electrons
An atom or group of atoms bearing an electrical charge such as the sodium and chlorine atoms in a salt solution.
Origin: From ἰόν, neuter present participle of εἶμι.
one of the elements which appear at the respective poles when a body is subjected to electro-chemical decomposition. Cf. Anion, Cation
Origin: [L. -io, acc. -ionem: cf. F. -ion.]
An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge. Ions can be created by both chemical and physical means. In chemical terms, if a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation. If an atom gains electrons, it has a net negative charge and is known as an anion. An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion. 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.
Chambers 20th Century Dictionary
ī′on, n. one of the components into which an electrolyte is broken up on electrolysis—the Anion, the electro-negative component, chemically attacking the anode, and the Cation, the electro-positive component, the cathode. [Gr. iōn, pr.p. of ienai, to go.]
The Nuttall Encyclopedia
in the Greek mythology son of Apollo by Creusa, and exposed by her in the cave where she bore him, but who was conveyed by the god to Delphi and educated by a priestess, and was afterwards owned by his mother, and became the ancestor of the Ionians, her husband, Xuthus, being kept throughout in the dark.
