One of the most stable nuclei is 55Mn. Its nuclidic mass is 54.938 u. Determine its total binding energy and average binding energy per nucleon. 

Average binding energy per nucleon AE/N for stable nuclei, as a function of atomic number A [5]. 

Since there are 12 nucleons (protons and neutrons), the average binding energy per nucleon is (92.1 MeV)/12, or 7.68 MeV. 

Fig. 2.1 Variation in average binding energy per nucleon as a function of mass number. Note that the energy scale is positive, meaning that the nuclei with the highest values of the binding energies release the greatest amount of energy upon formation.

If the average nucleon binding energy in this region is 7.57 MeV one can calculate the difference between this average binding energy and the one really observed in the formation of and Pu. Calculate this... 

Figure 24.14 shows the average binding energy per nucleon versus the mass number. Note that the binding energy per nucleon reaches a maximum around a mass number of 60. Elements with a mass number near 60 are the most stable. 

A Figure 21.12 Nuclear binding energies. The average binding energy per nucleon increases initially as the mass number increases and then decreases slowly. Because of these trends, fusion of light nuclei and fission of heavy nuclei are exothermic processes.
