Eon vs. Ion: What's the Difference?

An indefinitely long period of time; an age.

An atom or a group of atoms that has acquired a net electric charge by gaining or losing one or more electrons.

The longest division of geologic time, containing two or more eras.

An atom or group of atoms bearing an electrical charge, such as the sodium and chlorine atoms in a salt solution.

(US) Eternity.

An atom or goup of atoms (radical) carrying an electrical charge. It is contrasted with neutral atoms or molecules, and free radicals. Certain compounds, such as sodium chloride, are composed of complementary ions in the solid (crystalline) as well as in solution. Others, notably acids such as hydrogen chloride, may occur as neutral molecules in the pure liquid or gas forms, and ionize almost completely in dilute aqueous solutions. In solutions (as in water) ions are frequently bound non-covalently with the molecules of solvent, and in that case are said to be solvated. According to the electrolytic dissociation theory, the molecules of electrolytes are divided into ions by water and other solvents. An ion consists of one or more atoms and carries one unit charges 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.

A period of 1,000,000,000 years.

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.

(geology) The longest geochronologic unit, being a period of hundreds of millions of years; subdivided into eras.

A particle that is electrically charged (positive or negative); an atom or molecule or group that has lost or gained one or more electrons

A long period of time.

A spirit being emanating from the Godhead.

An immeasurable or infinite space of time; eternity; a long space of time; an age.

One of the embodiments of the divine attributes of the Eternal Being.

The longest division of geological time

An immeasurably long period of time

(Gnosticism) a divine power or nature emanating from the Supreme Being and playing various roles in the operation of the universe
