    Protons and neutrons reside in the atomic nucleus and account for almost all of the mass of the atom. The number of protons present in an atom’s nucleus, its atomic number, determines the identity of that atom as an element. The elements are numbered and arranged on the periodic table by their atomic numbers.

    The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.
