To perform the calculation, one must use the following formula: (b)x + (1-x)(c) = a and the unknown abundance is the "x.". "B" refers to the first isotope's atomic mass and "c" refers to the second isotope's atomic mass. To get an accurate answer, each isotope's atomic mass and the element's specific atomic mass are necessary.
Isotopes describe the periodic table's elements. It looks at two separate atoms with different neutron amounts and equal proton amounts and determines the differences between the two, in addition to varying neutron amounts. Isotope abundance describes how often different isotope arrangements within a single element happen.
