The largest atomic mass for an artificial element (or any element) would be Ununoctium. Neutronâ¦ stars, which are neutrons densely packed together surrounded by a thin layer of degenerate matter could possibly be considered atomic nuclei, though their specific proton count would probably not be measurable.
Atomic mass is approximately the sum of the number of protons andneutrons found in the nucleus of an atom. Basically atomic mass isthe weight of the neutrons and protons in onâ¦e atom. For elements with no stable isotopes, the mass number of theisotope with the longest half-life is considered the atomic mass ofthe element. Atomic mass is, roughly, the number of protons in addition to the number of neutrons (M = P + N).
