We usually distinguish the binding energy according to these levels:<\/p>\n
At the atomic level,<\/strong> the atomic binding energy of the atom derives from the electromagnetic interaction of electrons in the atomic cloud and nucleons (protons) in the nucleus. The atomic binding energy<\/strong> is the energy required to disassemble an atom into free electrons and a nucleus. This is more commonly known as ionization energy<\/strong>.<\/p>\n At the molecular level,<\/strong> the molecular binding energy of the molecule derives from the bond-dissociation energy of atoms in a chemical bond.<\/p>\n At the nuclear level,<\/strong> the nuclear binding energy is the energy required to disassemble (to overcome the strong nuclear force) a nucleus of an atom into its component parts (protons and neutrons<\/a>).<\/p>\n The component parts of nuclei are neutrons and protons, which are collectively called nucleons. The mass of a nucleus is always less than the sum masses of the constituent protons and neutrons when separated<\/strong>. The difference is a measure of the nuclear binding energy which holds the nucleus together. According to the Einstein relationship (E=m.c2<\/sup>) this binding energy is proportional to this mass difference, and it is known as the mass defect<\/strong>.<\/p>\nNuclear Binding Energy<\/h2>\n
