What is the average atomic mass of an atom? Average atomic mass is a measurement that describes the average mass of individual atoms in a given element. Elements can be made of isotopes which are atoms that differ in their numbers of neutrons, and therefore differ in their atomic mass. The...
Define Average atomic mass. Average atomic mass synonyms, Average atomic mass pronunciation, Average atomic mass translation, English dictionary definition of Average atomic mass. n. The mass of an atom, usually expressed in atomic mass units. American H
摘要: The continued use of the terms "standard atomic weight" and "atomic weight" (of any element), as opposed to "relative atomic mass" has attracted considerable controversy since at least the 1960s, mainly due to the technical difference between weight and mass in physics.(see below)....
