An element's average atomic mass is calculated by adding the masses of its isotopes and multiplying each by the element's natural abundance. Average atomic mass is equal to f1M1 + f2M2 +… + fnMn, where f is the fraction indicating the isotope's natural abundance and M is its mass number (weight). On the periodic table, an element's average atomic mass is usually listed beneath the elemental symbol. Calculating the average atomic mass of an element is simple when information on the natural abundance of the various isotopes of that element is available.
