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.
Why is the atomic mass of a element not a whole number like its atomic number and mass number? An element's atomic mass is not an integer (a whole number) because it is the average mass of all of the element's isotopes (elements that have different amounts of neutrons e â¦ ffecting the mass number of an element). For example, oxygen has 16.01 as its atomic mass.
