Question
The binding energy per nucleon of iron atom is approximately.
✓
Answer
The maximum binding energy per nucleon occurs at around mass number $A = 50,$ and corresponds to the most stable nuclei. Iron nucleus $F^{56}$ is located close to the peak with a binding energy per nucleon value of approximately $8.8\ \text{MeV}.$ It’s one of the most stable nuclides that exist.
