The periodic table lists two main numbers for each element. the atomic number is an integer that equals the number of protons. the number of neutrons is not given in the periodic table because it will vary with different isotopes. the mass number of an element is the sum of the protons and neutrons. to find the number of neutrons, the atomic number must be subtracted from the mass number.
