Heavy nucleus of atoms go through fission so that they can:
Correct answer: D. Increase their binding energy per nucleon
- A. Absorb low amount of energy
- B. Absorb high amount of energy
- C. Reduce their binding energy per nucleon
- D. Increase their binding energy per nucleon
Explanation
Maximum binding energy is achieved around Z = 50 (Iron is close to peak at Z = 56). Heavy nuclei undergo fission to decrease nuclear size and increase binding energy per nucleon.

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.
