The term "isotope", Greek for "at the same place", was suggested to Soddy by Margaret Todd, a Scottish physician and family friend, during a conversation in which he explained his ideas to her. He won the 1921 Nobel Prize in Chemistry in part for his work on isotopes.

This is because the chlorine-35 isotope is much more abundant than the chlorine-37 Normally, IRMS analysis of drugs of abuse involves the determination of the relative isotope abundances of hydrogen (1 H and 2 H), carbon (12 C and 13 C), nitrogen (14 N and N 15), and oxygen (16 O, 17 O, and 18 O). The terrestrial isotope ratios were determined when the earth was formed and are, for the most part, fixed. These isotopes are radioactive in nature and are, therefore, known as radioisotopes (or radionuclides). Examples of radioactive isotopes include carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238.
Fundamental properties of atoms including atomic number and atomic mass. The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.

nuclide. A nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon-13 with 6 protons and 7 neutrons. The nuclide concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, whereas the isotope concept (grouping all atoms of each element) emphasizes chemical over nuclear.
