  • Isotope - Wikipedia
    The three naturally occurring isotopes of hydrogen The fact that each nuclide has 1 proton makes them all isotopes of hydrogen: the identity of the isotope is given by the number of protons and neutrons From left to right, the isotopes are protium (1 H) with 0 neutrons, deuterium (2 H) with 1 neutron, and tritium (3 H) with 2 neutrons Isotopes are distinct nuclear species (or nuclides) of
  • Isotone - Wikipedia
    Isotopes are nuclides having the same number of protons: e g carbon-12 and carbon-13 Isobars are nuclides having the same mass number (i e sum of protons plus neutrons): e g carbon-12 and boron-12 Nuclear isomers are different excited states of the same type of nucleus A transition from one isomer to another is accompanied by emission or absorption of a gamma ray, or the process of
  • Isotope dilution - Wikipedia
    Isotope dilution analysis is a method of determining the quantity of chemical substances In its most simple conception, the method of isotope dilution comprises the addition of known amounts of isotopically enriched substance to the analyzed sample
  • Isotope analysis - Wikipedia
    Isotope analysis Magnetic sector mass spectrometer used in isotope ratio analysis, through thermal ionization Isotope analysis is the identification of isotopic signature, abundance of certain stable isotopes of chemical elements within organic and inorganic compounds
  • Radiochemistry - Wikipedia
    Radiochemistry Glovebox Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable)
  • Isotopologue - Wikipedia
    Isotopologue In chemistry, isotopologues (also spelled isotopologs) are molecules that differ only in their isotopic composition [1] They have the same chemical formula and bonding arrangement of atoms, but at least one atom has a different number of neutrons than the parent
  • Isotope geochemistry - Wikipedia
    Isotope geochemistry is an aspect of geology based upon the study of natural variations in the relative abundances of isotopes of various elements Variations in isotopic abundance are measured by isotope-ratio mass spectrometry, and can reveal information about the ages and origins of rock, air or water bodies, or processes of mixing between them Stable isotope geochemistry is largely
  • Radionuclide - Wikipedia
    A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that is unstable and known to undergo radioactive decay into a different nuclide, which may be another radionuclide (see decay chain) or be stable
