How to Find the Relative Abundance of Isotopes
Most elements come in multiple isotopes, atoms that have the same number of protons and electrons but different number of neutrons. Different isotopes react the same chemically, but their atomic weights are different; the atomic weights giv... Read More »

The relative isotopic mass is the relative mass of the isotope, scaled with carbon-12 as exactly 12. No other isotopes have whole number masses due to the different mass of neutrons and protons, as well as loss/gain of mass to binding energ...

The stable isotopes of antimony (Sb) are 121 Sb and 123 Sb We'll suppose that the lighter isotope is 121 Sb. Therefore it must be more abundant. The atomic mass of antimony is 121.760 121.760 = 120.904x + 122.904y (1) x is fractional abund...

This refers to the percentage of the stable isotopes of an element found in nature. For example C-12 is found at 98.90% and C-13 at 1.10%. Only the stable isotopes are considered when percent abundance is being discussed. So, for example, C...

Hi Marielle: Let x be the fraction of the lighter isotope then 126.6331x is the contribution the light isotope makes to the overall atomic weight. The remaining fraction (1-x) therefore contributes 129.1386(1-x) to the atomic weight which w...
