Isotopes, Physics

For each element the number of neutrons in the nucleus can vary.

Isotopes :Nuclei of given element with different numbers of neutrons.If they are not radioactive they called stable isotopes, and if they are radioactive they are called radioisotopes, for example carbon has two stable isotopes (12C and 13C ) and several radioisotopes  (e.g. 11C,14Cand 15C).
