Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes.Ionization, 
?
Radioactive metals emit particles and radiation from their nuclei. This process comes in the picture because their nuclei experience the intense conflict between two strong forces. This metal also have radioactive isotopes.Radioactive Isotopes,
