Binding Energy Per Nucleon Peak
Mediumphysics
Binding energy per nucleon highest around?
Select the correct option:
Solution
Incorrect! Answer:
Iron (Fe)
- Stability Measure: Binding energy per nucleon (BE/A) determines the stability of a nucleus. Higher BE/A means more stability.
- Binding Energy Curve: As we look at the curve of BE/A vs. Mass Number (A):
- It rises sharply for light nuclei.
- It reaches a maximum of about 8.8 MeV per nucleon.
- Peak Identity: The peak occurs for elements like Iron (56Fe).
- Consequences: Nuclei lighter than iron tend to undergo fusion, and those much heavier tend toward fission to reach this more stable configuration.
