isotope

 [i´so-tōp]
a chemical element having the same atomic number as another (i.e., the same number of nuclear protons), but having a different atomic mass (i.e., a different number of nuclear neutrons).
radioactive isotope radioisotope.
stable isotope one that does not transmute into another element with emission of corpuscular or electromagnetic radiations.

sta·ble i·so·tope

a nonradioactive nuclide; an isotope that shows no tendency to undergo radioactive decomposition.
