Any process by which an atom or molecule gains or loses electrons.

An atom or molecule is said to be ionised when it has gained or lost one or more electrons. If an atom or molecule gains an electron, it is negatively charged (see anion*); losing an electron makes it [..]

Ionisation is the process where by an Atom or molecule gains or looses an Electron and thus becomes an Ion . Ionising Radiation has sufficient energy to be able to ionise atoms and molecules and thus [..]

Ionisation is any process which causes the addition of one or more extra electrons to the atomic shell or the elimination of one or more electrons from the atomic shell. The addition of electrons results in negatively charged ions (Anions) and the elimination results in positively charged ions (cations). A plasma stimulation process causes the ioni [..]

Ionisation is the process by which an electron is removed or added to an atom, leaving the atom with a nett negative charge (negative ion) or a nett positive charge (positive ion). A process of formation of ions.
