Binding Energy vs Mass Defect
Fórmula
## Nuclear Binding Energy Binding energy is the energy required to disassemble a nucleus into free protons and neutrons. ### Formula **E = delta_m * c²** Using atomic mass units: **E (MeV) = delta_m (u) * 931.494 MeV/u** The mass defect delta_m is the difference between the sum of individual nucleon masses and the actual nuclear mass.
Ejemplo Resuelto
Helium-4 nucleus with mass defect 0.03437 u.
- 01E = delta_m * 931.494 MeV/u
- 02E = 0.03437 * 931.494
- 03E = 32.02 MeV
- 04E per nucleon = 32.02 / 4 = 8.005 MeV/nucleon
Preguntas Frecuentes
What is mass defect?
The mass of a nucleus is always less than the sum of its individual protons and neutrons. This missing mass has been converted to binding energy.
Which element has the highest binding energy per nucleon?
Iron-56 at about 8.8 MeV/nucleon. This is why iron is the endpoint of stellar fusion and why both fusion (light elements) and fission (heavy elements) release energy.
How does binding energy relate to nuclear stability?
Higher binding energy per nucleon means a more stable nucleus. Nuclei near the iron peak are the most tightly bound and stable.
