Define atomic mass. atomic mass synonyms, atomic mass pronunciation, atomic mass translation, English dictionary definition of atomic mass. n. The mass of an atom, usually expressed in atomic mass units. American Heritage® Dictionary of the English La
This gave a different set of relative masses for the elements. The inadequacy of oxygen as an arbitary standard led to the selection of the carbon-12 isotope of carbon as the arbitary standard. The relative atomic mass of an element is defined as the weight in grams of the number of ...

Chlorine, for example, has an atomic mass value of 35.453 u, while copper has one of 63.54 u. These values of the atomic masses can be explained by the effect of the relative abundances of the isotopes of the elements contributing to produce the observed net mass. If an element consists ...
Atomic Mass of First 30 Elements - Atomic Mass of Elements is Measured with the Help of its Unit - Atomic Mass Unit. One such Unit is Equal to One-Twelfth of the Mass of a Carbon-12 Atom Which is at Rest. Learn about Atomic Mass of First 30 Elements at B
