The amount of energy required to break the nucleus into constituent nucleons is called;
Correct answer: C. Binding energy
- A. Excitation energy
- B. Ionization energy
- C. Binding energy
- D. Work function
Explanation
Binding energy is the amount of energy required to break a nucleus into its nucleons (protons and neutrons). It represents the strength of the nuclear forces that hold the nucleons together within the nucleus.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
