The binding energy per nucleon for stable, medium. mass nuclei is approximately constant at:
Correct answer: A. 8 MeV per nucleon
- A. 8 MeV per nucleon
- B. 7 MeV per nucleon
- C. 6 MeV per nucleon
- D. 9 MeV per nucleon
Explanation
The curve of binding energy shows that for nuclei with mass numbers from about 30 to 170, the binding energy per nucleon is relatively constant, plateauing at about 8 to 8.75 MeV. This region includes the most stable elements.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
