Explore: Radioactive Isotopes

radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that is unstable and known to undergo radioactive decay into a different

formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which

In isotopic labeling, there are multiple ways to detect the presence of labeling isotopes; through their mass, vibrational mode, or radioactive decay

elements in the periodic table, 80 have isotopes considered to be stable. Overall, there are 251 known stable isotopes in total. Atomic nuclei consist of protons
