Periodic table with average atomic mass
WebJul 28, 2015 · Because of the proton/neutron mass difference, we still wouldn't have integer values. Carbon 12 has a 1:1 ratio of protons to neutrons. In the absence of any difference in binding energy per nucleon, any isotope with a 1:1 proton to neutron ratio would have an integer atomic mass, but an isotope with any other ratio would not. – Will Orrick. WebMar 6, 2024 · Average atomic mass Ag = (mass Ag-107 * abundance Ag-107) + (mass Ag-109 * abundance Ag-109) =(106.90509 * 0.5186) + (108.90470 * 0.4814) = 55.4410 + …
