What is Ionization?
Ionization is the process by which an atom, molecule, or ion gains or loses electrons to become an electrically charged species (an ion). The energy required to remove the outermost electron from a neutral gaseous atom is called the first ionization energy. Ionization can occur through thermal energy, radiation (photoionization), or chemical reactions (autoionization, acid-base reactions).
