n.

1. The formation of or separation into ions by heat, electrical discharge, radiation, or chemical reaction.
2. The state of being ionized.

The process by which an electron is removed from an atom, molecule, or ion. It is of basic importance to electrical conduction in gases and liquids. In the simplest case, ionization may be thought of as a transition between an initial state consisting of a neutral atom and a final state consisting of a positive ion and a free electron. In more complicated cases, a molecule may be converted to a heavy positive ion and a heavy negative ion which are separated.

---

The process whereby the positive and negative ions of a salt or other compound separate when dissolved in water. The degree of ionization of an acid or alkali determines its strength (see ph).

(ī'-änizā'shən)
n

The process or the result of a process by which a neutral atom or molecule acquires either a positive or negative charge.

1. the dissociation of a substance in solution into ions.
2. iontophoresis.

• i. chamber — an enclosure containing two or more electrodes between which an electric current may be passed when the enclosed gas is ionized by radiation; used for determining the intensity of x-rays and other rays.

IN BRIEF: Conversion wholly or partly into an atom that has a positive or negative charge.

The chemistry students demonstrated a simple ionization experiment.
