Why is 56Fe26 considered one of the most stable nuclei?
Correct answer: B. It has the highest binding energy per nucleon
- A. It has the highest number of protons
- B. It has the highest binding energy per nucleon
- C. It undergoes spontaneous fission
- D. It has equal numbers of protons and neutrons
Explanation
26Fe56 has one of the highest binding energies per nucleon (~8.79 MeV), indicating strong nuclear stability. High binding energy means more energy is required to break the nucleus apart, making it less likely to undergo spontaneous decay.

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.
