| atomic w. |
the sum of the masses of the constituents of an atom, either that of a single isotope or that obtained using weighted averages of the masses of the natural isotopes. It can be expressed in atomic mass units (or daltons), in SI units (i.e., kilograms), or as a dimensionless ratio derived by comparing the mass to the mass of the 12C isotope of carbon, which is defined as exactly 12.000. Abbreviated at wt. Called also atomic mass.
