Atoommassa
De atoommassa (ma) is de massa van een atoom, uitgedrukt in atomaire massa-eenheden (u). De nuclidenmassa van een nuclide is de atoommassa hiervan. De nuclidenmassa is bij benadering een geheel getal, namelijk het massagetal van het nuclide. De nuclidenmassa verminderd met het massagetal wordt het mas… WebGeeft aan hoe vaak de absolute atoommassa van die atoomsoort groter is dan de internationale atoommassa-eenheid.

The atomic mass (ma or m) is the mass of an atom. Although the SI unit of mass is the kilogram (symbol: kg), atomic mass is often expressed in the non-SI unit dalton (symbol: Da) – equivalently, unified atomic mass unit (u). 1 Da is defined as 1⁄12 of the mass of a free carbon-12 atom at rest in its ground state. The … See more Relative isotopic mass (a property of a single atom) is not to be confused with the averaged quantity atomic weight (see above), that is an average of values for many atoms in a given sample of a chemical element. See more The amount that the ratio of atomic masses to mass number deviates from 1 is as follows: the deviation starts positive at hydrogen-1, … See more Similar definitions apply to molecules. One can calculate the molecular mass of a compound by adding the atomic masses (not the standard atomic weights) of its constituent atoms. Conversely, the molar mass is usually computed from the standard atomic weights See more • Atomic number • Atomic mass unit • Isotope • Isotope geochemistry • Molecular mass • Jean Stas See more The atomic mass or relative isotopic mass are sometimes confused, or incorrectly used, as synonyms of relative atomic mass (also known as atomic weight) or the standard atomic weight (a particular variety of atomic weight, in the sense that it is standardized). … See more Direct comparison and measurement of the masses of atoms is achieved with mass spectrometry.
