Iron has a mass number of 56 and is one of the most stable of all the elements. We say that iron has a high binding energy per nucleon. Elements with lower and higher mass numbers per nucleon are ...

A calculated binding energy, for example, may well be reported in kcal./mol. or eV. on one hand, or in Rydbergs or Hartree atomic units (double Rydbergs) on the other. The latter pair have the ...
