The generation of one or more ions. It may occur, e.g. by loss of an electron from
a neutral
molecular entity, by the
unimolecular heterolysis of such an entity into two or more ions, or by a heterolytic
substitution reaction involving neutral molecules, such as:
The loss of an electron from a singly, doubly, etc. charged
cation is called second, third, etc
. ionization. This terminology is used especially in
mass spectroscopy.
