WebThe modern periodic table. an atomic number is the number of protons in the nucleus of an atom. elements are arranged in order of increasing atomic number. Periodic tables show relative atomic masses, Ar, rather than atomic masses. These are the weighted mean mass of the atoms of each element, compared to one-twelfth the mass of a carbon-12 atom.
