Questions and Answers

What is the nuclear binding energy in experimental physics?

  • The energy released when the nucleus was formed
  • The energy balance in processes in which the nucleus splits into fragments composed of more than one nucleon
  • The energy required to combine protons and neutrons to form a nucleus
  • The minimum energy required to disassemble the nucleus of an atom into its constituent protons and neutrons (correct)

    • Why is the nuclear binding energy for stable nuclei always a positive number?

  • The nucleus must gain energy for the nucleons to move apart from each other (correct)
  • The strong nuclear force repels the nucleons from each other
  • The mass of an atomic nucleus is greater than the sum of the individual masses of the free constituent protons and neutrons
  • The energy released when the nucleus was formed is positive

    • In theoretical nuclear physics, how is the nuclear binding energy considered?

  • A positive number representing the energy released when the nucleus was formed
  • A positive number representing the energy required to combine protons and neutrons to form a nucleus
  • A negative number representing the energy of the nucleus relative to the energy of the constituent nucleons when they are infinitely far apart (correct)
  • A positive number representing the energy balance in processes in which the nucleus splits into fragments composed of more than one nucleon

    Study Notes

    Nuclear Binding Energy

    • Nuclear binding energy is the energy required to separate a nucleus into its constituent protons and neutrons.

    Stability of Nuclei

    • The nuclear binding energy for stable nuclei is always a positive number, indicating that energy is required to break the nucleus into its individual components.

    Theoretical Nuclear Physics

    • In theoretical nuclear physics, the nuclear binding energy is considered as the difference between the mass of the nucleus and the sum of the masses of its individual protons and neutrons.

    Mass Defect and Missing Mass

    • The term "mass defect" refers to the difference between the sum of the masses of individual protons and neutrons and the mass of the nucleus they form.
    • The "missing mass" in a nucleus can be calculated by subtracting the mass of the nucleus from the sum of the masses of its individual protons and neutrons.
