12.2 Nuclear Binding Energy

Learning Objectives

  • Calculate the mass defect and binding energy for a wide range of nuclei
  • Use a graph of binding energy per nucleon (BEN) versus mass number (𝐴) graph to assess the relative stability of a nucleus
  • Compare the binding energy of a nucleon in a nucleus to the ionization energy of an electron in an atom

Practice!
