Goes over the required values of mass and energy for the neutron, proton, electron and hydrogen atom. Values are given in kilograms (kg), unified atomic mass units (u) and mega electron volts (MeV).
The mass of an atomic nucleus is less than the sum of the individual masses of the free constituent protons and neutrons, according to Einstein's equation E = mc2. Nuclear binding energy is the minimum energy that would be required to disassemble the nucleus of an atom into its component parts. These component parts are neutrons and protons, which are collectively called nucleons. The binding energy is always a positive number, as we need to spend energy in moving these nucleons, attracted to each other by the strong nuclear force, away from each other. This 'missing mass' is known as the mass defect, and represents the energy that was released when the nucleus was formed.
Also includes a worked example problem problem for calculating mass defect and binding energy.
