s defect (Podgorsak 17), in a nucleus comes about due to the fact that under normal convection, the mas of the protons and nucleons is assigned a rounded off value, 1, which is not the actual mass of the neutrons nor the protons. The mass of a proton is equal to 1.00728 u, where u represents the atomic mass unit (amu), whereas that of a neutron is equal to 1.00866 u. Summation of the masses in the nucleus, mass of individual nucleons in the nucleus, should represent the actual mass, but the measurable mass is always less. This inequality results to a phenomenon in the atomic properties referred to as the mass defect.
The values obtained from the calculations above are as expected, with knowledge of the atomic structure and the expected differences in the atomic radius of the atoms; my deduction was that the larger the radius of the atom, the higher the binding energy needed to hold the atom together. The difference in the binding energy between Fe56 and Ra226 is associated to the difference in the atomic weight of the atoms. The atom that has a higher number of nucleons requires higher energy to keep the nucleus at its short rage. From the calculations of the binding energy, the higher the number of nucleons in the nucleus, particularly the neutron, results to a higher difference in the mass defect, which translates to high values of the binding energy.
From the definition of biding energy as the energy that holds the nucleons together to form the nucleus, the k shell electron in the tungsten experiencing 69.5 KeV is at the stable element state. Tungsten (W74) is made up of 74 protons or electrons and 110 neutrons. The atomic mass of the atom is 183.84 u, but by using the nucleons, we can get the mass defect:
From the bidding energy calculated above, the binding energy to the K shell electron is a mere fraction of the total biding energy by the nucleus. The biding energy that the electron may be experiencing may be 69.5 KeV, which is the energy needed to
