Atomic mass constant — In physics and chemistry, the atomic mass constant, m u, is one twelfth of the mass of an unbound atom of the carbon 12 nuclide at rest and in its ground state. [GoldBookRef|title=atomic mass constant|url=http://goldbook.iupac.org/A00497.html] It … Wikipedia
Atomic mass — The atomic mass (ma) is the mass of an atom, most often expressed in unified atomic mass units. [GoldBookRef|file=A00496|title=atomic mass] The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom … Wikipedia
atomic mass — Chem. the mass of an isotope of an element measured in units formerly based on the mass of one hydrogen atom taken as a unit or on 1/16 the mass of one oxygen atom, but after 1961 based on 1/12 the mass of the carbon 12 atom. Abbr.: at. m. [1895… … Universalium
