The process of removal or attachment of electrons to atoms or molecules to form positive or negative ions, respectively.

The gain or loss of an electron in an atom.

the condition of being dissociated into ions (as by heat or radiation or chemical reaction or electrical discharge); "the ionization of a gas"

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

The process by which a neutral atom or molecule loses or gains an electrical charge resulting in the production of an ion.

sufficient energy is deposited in a neutral molecule to displace an electron, thus replacing the neutral molecule with positive and negative ions.

A thelassotherapy where the seawater is ionised with negative ions and is inhaled or sprayed. Used to heal the upper respiratory tract.

process by which an atom or molecule acquires or loses an electric charge and becomes an ion

An atom or molecule is said to be ionised when it has gained or lost one or more electrons. If an atom or molecule gains an electron, it is negatively charged (see anion*); losing an electron makes it positive (see cation*). Click here to go back to where you were.
