- Autoionization
Autoionization is a process by which
atoms ormolecules spontaneously transition from an electrically neutral state to a lower-energyionized state..Atoms can autoionize when the two outer
electrons are bothexcited and, throughelectrostatic interactions, one of the electrons is ejected, ionizing the atom.For an example of molecular autoionization, see
self-ionization of water .Other examples are given by the autoionization of core-excited molecules, see
Auger effect , or ofRydberg atom s.Autoionizing states are
resonance s.More specifically, autoionization refers to non-
redox ionization of a molecular substance. Seemolecular autoionization ee also
