The stability of an ion can be determined by viewing the outermost valance shell.If the shell contains 8 electrons it is said to be stable (octet rule) , if not the particular ion is unstable.Stable isotopes can spontaneously undergo changes, transforming them into other isotopes of the same or of different elements.
