WebIsotopes. Calculating the neutrons in an element. The nucleus of any element comprises a set of neutrons and protons. A total number of neutrons and protons together make the mass number of the element, since they both have a mass of 1 unit. Hence, if we know the mass number and the atomic number (Since the atomic number is equal to the number of … WebStable Isotope Geochemistry is an introduction to the use of stable isotopes in the geosciences. It is subdivided into three parts: theoretical and experimental principles; fractionation processes of light and heavy elements; the natural variations of geologically important reservoirs.
