Nuclear Binding Energy II Calculate the binding energy per nucleon for the nucleus. (Atomic masses: iron-56 = 55.9349 amu; hydrogen-1 = 1.0078 amu; mass of neutron = 1.0087 amu) 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 56Fe nucleus is "synthesized" from 26 protons and 30 neutrons, we see that Am = (55.9349 - 26 me) - [26(1.0078 - me) + 30(1.0087)]. Solve for Am. Am = -0.5289 amu Submit What is the energy change? AE = -7.9x10^-11 J/nucleus Submit What is the binding energy (BE) per nucleon? BE per nucleon = X MeV/nucleon

A student is surprised by her work. She feels that the nuclear binding energy is high for oxygen-16. Her work is as follows: Part 1: One neutron's mass is 1.008665 amu, while one proton's mass is 1.007276 amu. In oxygen - 16 there are 8 protons and 8 neutrons with a total mass of 16.127528 amu. (1.007276x8)+(1.008665x8)=16.127528 Part 2: Because the mass of oxygen-16 is 15.994915 amu, the difference between the mass of an atom and the sum of its protons and neutrons is the mass defect. The mass defect for oxygen-16 is 0.132613 amu. 16.127528-15.994915 0.132613 Part 3: The missing mass in oxygen-16 is converted to the nuclear binding energy using Einstein's equation E = mc². The amount of energy is 1.19x1016 J, which I think is too high. E = mc² = (0.132613) × (3.00 x 108)2=1.193×1016 J Which part of the solution was there an error? a) Parts 2 and 3. b) Part 3 only. c) Parts 1 and 2. d) No error.
