MCQ
The binding energy per nucleon of iron atom is approximately.
  • A
    13.6eV
  • B
    8.8MeV
  • C
    Infinity
  • D
    10MeV

Answer

  1. 8.8MeV

Explanation:

The maximum binding energy per nucleon occurs at around mass number A = 50, and corresponds to the most stable nuclei. Iron nucleus F56 is located close to the peak with a binding energy per nucleon value of approximately 8.8MeV . It’s one of the most stable nuclides that exist.
