Meaning
The binding energy of a nucleus is the work that must be done to separate a nucleus into its constituent neutrons and protons.
About Binding Energy of a Nucleus
- Binding energy = mass defect × c².
- Binding energy measured in MeV.
- Binding energy indicates the stability of the nucleus with a higher binding energy indicating a more stable nucleus.
- binding energy per nucleon represents the energy required to disassemble a nucleus into individual nucleons.
- The curve of binding energy per nucleon versus mass number shows a peak at iron (Fe-56).
Examples
- Helium-4 has a high binding energy per nucleon, making it very stable.
- Nuclear fusion and fission involve changes in binding energy, releasing energy.
