All atoms with nuclei containing the same number of protons have identical chemical properties and are called isotopes of the element in question. Isotopes may be radioactive or stable. Thus, some radionuclides share their chemical properties with stable isotopes. 4, record 1, English, - stable%20isotope

Studies of metabolism, drug utilization, and other reactions in living organisms are best done with stable isotopes like13C,15N,18O, and2H. Compounds are tagged by introducing a high concentration of the isotope into the molecular structure, and the metabolized products are studied using the mass spectrometer to measure the altered isotopic ratios. 3, record 2, English, - heavy%20isotope
