Key Stage 5
Meaning
The binding energy per nucleon is the average work done per nucleon to separate a nucleus into its constituent parts.
About Binding Energy Per Nucleon
Calculated as the total binding energy of the nucleus divided by the mass number. Highest for nuclei with a mass number around 56 (iron). Indicates how tightly nucleons are held together in the nucleus. Affects the energy released in nuclear reactions.
Examples
Iron-56 has the highest binding energy per nucleon, making it the most stable nucleus. Uranium-235 has lower binding energy per nucleon, making it suitable for fission.
