Calculate the binding energy in J/nucleon for carbon-12 (atomic mass 12.00000) and uranium-235 (atomic mass 235.0439). The atomic mass of 11H is 1.00782 amu, and the mass of a neutron is 1.00866 amu. The most stable nucleus known is 56Fe. Would the binding energy per nucleon for 56Fe be larger or smaller than that for 12C or 235U? Explain.
