Ionize: become converted into ions
(ionisation) ionization: the condition of being dissociated into ions (as by heat or radiation or chemical reaction or electrical discharge); "the ionization of a gas"
Ionization is the physical process of converting an atom or molecule into an ion by adding or removing charged particles such as electrons or other ions. This is often confused with dissociation (chemistry).
Alternative spelling of ionize
(ionised) molecules and atoms separated from some or all of their circulating electrons
(Ionisation) The gain or loss of an electron in an atom.
(Ionisation) A thalassotherapy where the sea water is ionised with negative ions and is inhaled or sprayed. Used to heal the upper respiratory tract.
(Ionisation) Removal of an electron from a neutral atom or molecule, creating a positively charged ion. These atoms recombine very quickly and can cause biological effects in cells. One cause of ionisation is exposure to radioactive particles or rays.
The process involving either the addition or removal of electrons from an atom or molecule to form an ion. An ion carries a positive or negative charge.
