Binding energy
Definition
Binding energy is the energy required to disassemble a nucleus into its constituent protons and neutrons. It is a measure of the stability of a nucleus; the higher the binding energy, the more stable the nucleus.
5 Must Know Facts For Your Next Test
- Binding energy per nucleon is highest for iron-56, making it one of the most stable nuclei.
- In nuclear fusion, light nuclei combine to form a heavier nucleus, releasing binding energy.
- In nuclear fission, a heavy nucleus splits into smaller nuclei, also releasing binding energy.
- The mass defect in a nucleus is converted to binding energy according to Einstein's equation E=mc^2.
- The Sun generates energy through nuclear fusion processes that convert hydrogen into helium and release binding energy.
Review Questions
- What does binding energy indicate about the stability of a nucleus?
- How is binding energy related to both nuclear fusion and fission?
- Why is iron-56 considered one of the most stable nuclei based on binding energy?
