1) For this exercise the mass excess is used. The needed values are:
2) Calculate the binding energy per nucleon for ^{24}Mg by using a table or database for atomic mass excess.
3) What is the ratio between the nuclear binding energy and the electron binding energy for ^{23}Na when the ionization potential of sodium is 5.14 V?
4) Use Einstein’s formula to calculate the mass in kg of the following particles (n = 939.6 MeV, e = 0.511 MeV, u = 931.5 MeV):
5) Calculate the average binding energy, given in MeV of the nucleons in the following nuclei:
6) Assume a ^{233}U nucleon fissions into a ^{131}Xe nucleus, a ^{101}Ru nucleus and 3 neutrons. What are their respective energies?
7) Assume 200 MeV releases per nucleus when uranium fissions. How far can you drive a car with 1 g of ^{235}U as fuel when a car uses approximately 1 L of gasoline (density 0.70 g/cm^{3}) for every 10 km? The heat of burning for octane is 5500 kJ/mole and a gasoline engine can utilize 18% of the total energy.
8) Calculate the amount of energy released between a reaction of hydrogen and oxygen compared to the energy released with the creation of He from neutrons and hydrogen (proton + electron).
9) Determine if fusion of deuterium to helium gives more or less energy per gram than fission of uranium.
10) Explain why we never find more than one stable nuclei in isobar chains with odd number of nucleons, while isobar chains with even number of nucleons can have more than one.
11) Explain where we find nuclei with both β^{+} and β^{-} disintegration. Why do these nuclei have odd number of protons and odd number of neutrons?
