WebAs stated previously, the number of isotopes and their percent abundance are all that are needed to calculate the atomic weight of an element. We can start by using magnesium as an example. Magnesium has three naturally occurring isotopes: 24 Mg, 25 Mg, and 26 Mg. Each isotope has an abundance of 78.70 %, 10.13%, and 11.17%, respectively.
