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.
6) Iodine is 80% 127I, 17% 126I, and 3% 128I. Calculate the average atomic mass of iodine. 7) Calculate the average atomic mass of gold with the 50% being gold-197 and 50% being gold-198. 8) Hydrogen is 99% 1H, 0.8% 2H, and 0.2% 3H. Calculate its average atomic mass.
