IONIZATION

Ionization

Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons. Ionization, often, results from the interaction of an atom or a molecule with an ionizing particle, including charged particles with sufficient energies and energetic photons. A rare case of ionization in the absence of an external particle is the internal conversion process, through which an excited nucleolus transfers its energy to one of the inner-shell electrons and ejects it with high kinetic energy.
