Nucleons The term nucleon refers to the particles found in the nucleus of an atom, namely protons and neutrons. A single hydrogen atom (one proton plus one electron) has a mass of 1.007825 amu. A single neutron has a mass of 1.008665 amu. Note that amu stands for "atomic mass unit" and is sometimes abbreviated with the symbol u. 1 u is equivalent to 1.6605387Ã10â27 kg. Mass Defect The total mass of the individual nucleons in an atom is always greater than the actual measured mass of the atom. The difference is called the mass defect. Binding Energy The mass defect of an atom corresponds to an amount of energy called the binding energy. Binding energy can be calculated using Einstein's equation, E=mc2., where E is energy in joules, m is mass is kilograms, and c is the speed of light, 2.998Ã108 m/s.
