\i"on\ (?), n. [gr. &?;, neut, of &?;, p. pr. of &?; to go.] (elec. chem.) one of the elements which appear at the respective poles when a body is subjected to electro-chemical decomposition. cf. anion, cation.

1. one of the electrified particles into which, according to the electrolytic dissociation theory, the molecules of electrolytes are divided by water and other solvents. an ion consists of one or more atoms and carries a unit charge of electricity, 3.4 x 10-10 electrostatic units, or a multiple of this. those which are positively electrified (hydrogen and the metals) are called cations; negative ions (hydroxyl and acidic atoms or groups) are called anions.
note: thus, hydrochloric acid (hcl) dissociates, in aqueous solution, into the hydrogen ion, chformh^ + c/hform, and the chlorine ion, chformcl^ - c/hform; ferric nitrate, fe(no3)3 , yields the ferric ion, chformfe^ +++ c/hform, and nitrate ions, chformno3^ - c/hform, chformno3^ - c/hform, chformno3^ - c/hform. when a solution containing ions is made part of an electric circuit, the cations move toward the cathode, the anions toward the anode. this movement is called migration, and the velocity of it differs for different kinds of ions. if the electromotive force is sufficient, electrolysis ensues: cations give up their charge at the cathode and separate in metallic form or decompose water, forming hydrogen and alkali; similarly, at the anode the element of the anion separates, or the metal of the anode is dissolved, or decomposition occurs.
2. 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.

Ion
An electrically charged atom or group of atoms.

ION
(1) An atom or molecule that carries a net charge (either positive or negative) because of an imbalance between the number of protons and the number of electrons present. If the ion has more electrons than protons, it has a negative charge and is called an anion; if it has more protons than electrons it has a positive charge and is called a cation. (2) (Water Quality) An electrically charged atom that can be drawn from waste water during electrodialysis.

Ion
Ion (Greek) Son of Apollo and Creusa, the daughter of Athenian king Erechtheus. Exposed by his mother at birth, he was taken by Hermes to be brought up by the Delphic priestesses. Eventually reconciled with his mother and her second husband, he became ruler of the Aegialeans, afterwards called Ionians, and of Athens. From his four sons came the four Ionic tribes. {BCW 5:215}

Ion
An atom that has lost or gained one or more electrons and has become electrically charged as a result.

Ion
is an atom or molecule that has acquired an electric charge by the loss or gain of one or more electrons. :isothermal means of or indicating equality of temperature. :isotherms are lines connecting points of equal temperature on a weather map.

Ion
An atom which has either lost or gained one or more electrons. A positive ion remains if an electron is removed, for example, by being struck by a photon or fast charged particle of sufficient energy to overcome the binding energy of that electron.

ION
An atom or group of atoms that is electrically charged.

Ion
An electrically charged atom.

Ion
An atom or molecular fragment that has a positive electrical charge due to the loss of one or more electrons; the simplest ion is the hydrogen nucleus, a single proton.

ion
"An electrically charged chemical particle (atom, molecule, or molecule fragment). ""Anions"" are negatively charged, and ""cations"" are positively charged. "

ION
An atom or radical in solution carrying an integral electric charge, either positive (cation) or negative (anion).

Ion
An atom, molecule or compound that carries either a positive (cation) or negative (anion) electrical charge.

Ion
An atom that has lost or gained one or more electrons and has become electrically charged as a result.

ion
A particle obtained by adding or removing electrons from atoms or molecules. An atom or molecule with missing electrons has a net positive charge and is called a cation ; one with extra electrons has a net negative charge and is called an anion .

ion
an atom with a positive charge because it has had electrons removed or a negative charge because it has had electrons
added.

Ion
Atom or group of atoms that has acquired an electric charge through the gain or loss of an electron or electrons

Ion
an atom that has fewer or more electrons than it has protons causing it to have an electrical charge and, therefore, be chemically reactive.
