Difference atomic mass and atomic weight
WebThe atomic mass (relative isotopic mass) of an uncommon isotope can differ from the relative atomic mass, atomic weight, or standard atomic weight, by several mass units. Relative isotopic masses are always close to whole-number values, but never (except in the case of carbon-12) exactly a whole number, for two reasons: WebJul 30, 2016 · Atomic mass: The combined mass of all the nucleons present in the atom of any given element(Unit: amu/u).
