ionization

The formation of or separation into ions by heat, electrical discharge, radiation, or chemical reaction.

The state of being ionized.

In physical chemistry: The electrolytic dissociation of an electrolyte by solution or by fusion.

The process by which a gas is converted into a conductor of electricity; the state or condition of being ionized. See electron, 2, electron theory.

the process of converting neutral atoms or molecules into ions. The process may occur by dissolving an ionic substance in a dissociating solvent, such as water, or by adding or subtracting an electron to or from an atom or molecule. The latter process occurs, for example, in an electron beam in a mass spectrometer and by interaction of substances with ionizing radiation.

any process that leads to the dissociation of a neutral atom or molecule into charged particles ions; the state of being ionized

the condition of being dissociated into ions (as by heat or radiation or chemical reaction or electrical discharge)

the process of ionizing; the formation of ions by separating atoms or molecules or radicals or by adding or subtracting electrons from atoms by strong electric fields in a gas
