[Kererences) INTERACTIVE EXAMPLE Nuclear Binding Energy I Calculate the binding energy per nucleon for the Fe nucleus. (Atomic masses: iron-56 = 55.9349 amu; hydrogen-1 = 1.0078 amu; mass of neutron = 1.0087 amu) HOW DO WE GET THERE? We must first calculate the mass defect (Am) for 56Fe. Since atomic masses (which include the electrons) are given, we must decide how to account for the electron mass: 55.9349 mass of Fe atom = mass of nucleus + 26 me 1.0078 mass of H atom = mass of nucleus + me Thus, since a 6Fe nucleus is "synthesized" from 26 protons and 30 neutrons, we see that Am = (55.9349 - 26 m.) - [26(1.0078 - me) + 30(1.0087)1. Solve for Am.
