CHEM - A process by which a neutral atom or molecule loses or gains electrons, thereby acquiring a net charge and becoming an ion; occurs as the result of the dissociation of the atoms of a molecule in solution (NaCl->Na+ + Cl-) or of a gas in an electric field (H2->2H+). [McGraw-Hill Dictionary of Science & Technical Terms 3rd ed.]

The splitting up of molecules into ions. Ionization may apply either to a chemical compound or to a gas. When an electric current is passed through an electrolyte the constituents of the electrolyte which are liberated or deposited at the electrodes are called ions and this process is called ionization. Gases at or near atmospheric pressure are normally good insulators. They are said to undergo ionization when they are made conductive, that is when they allow the flow of electricity. A gas may be made conductive by passing X-rays through it, by the action of ultraviolet light, by subjecting it to radium rays, by passing it close to a flame or hot piece of metal or by forming in it a brush discharge or corona. Gases which have been made conductive carry current because of their dissociation into ions, which carry positive or negative charges of electricity. [Gernsback, Sidney, Radio Encyclopedia, 1927]

"ionization is an expression of radiational variation." [Russell, The Universal One, page 130]

"Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes. Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules and ions, or through the interaction with light. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected."
