There are three isotopes of phosphorus. Only one of them is stable. Calculate the binding energy per nucleon (in MeV) for P-32 (atomic mass = 31.9739 u). mass H = 1.007825 u and mass n = 1.008665 u.
There are three isotopes of phosphorus. Only one of them is stable. Calculate the binding energy per nucleon (in MeV) for P-32 (atomic mass = 31.9739 u). mass H = 1.007825 u and mass n = 1.008665 u.
Solution
Mass of particles in I-131 nucleus
15 protons x 1.0073 amu/proton =15.1095 amu
17neutrons x 1.0087 amu/neutron =17.1479 amu
Total mass of particles = 32
Mass defect = 32.2574 -32 = 0.2574 amu
E = mc^2 = 2.345
