WebIsotopes. Calculating the neutrons in an element. The nucleus of any element comprises a set of neutrons and protons. A total number of neutrons and protons together make the mass number of the element, since they both have a mass of 1 unit.

They share almost the same chemical properties, but differ in mass and therefore in physical properties. There are stable isotopes, which do not emit radiation, and there are unstable isotopes, which do emit radiation. The latter are called radioisotopes.
