The atomic mass number of an isotope represents the sum of the numbers of neutrons and of protons in a nucleus of the isotope. For elements with more than one stable (non-radioactive) isotope naturally occurring, the atomic mass of the element as shown in a reference is the weighted average of the atomic masses of all the naturally occurring isotopes, weighted by the fraction that each isotope constitutes of the total natural supply of the element.
