    Most periodic tables include a value for atomic mass (also called atomic weight) on each element tile. For a single atom of an element, this would be a whole number, adding the number of protons, neutrons, and electrons together for the atom. However, the value given in the periodic table is an average of the mass of all isotopes of a given ...
