WebAug 6, 2024 · The atomic mass on the periodic table is a weighted average of the atomic masses of atoms observed in all samples of that element. You can use the atomic abundance to calculate the atomic mass of any …
WebIsotopes are atoms of the same element with different numbers of neutrons. Because they contain different numbers of neutrons, isotopes have different atomic masses. The average atomic mass of an element is calculated by taking the weighted average mass of the element's naturally occurring isotopes. Created by Sal Khan. Sort by: Top Voted Questions
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.
