Explain the release of energy in nuclear fission and fusion on the basis of binding energy per nucleon curve.

उत्तर
The binding energy of each nucleon and a portion of its mass are transformed and released as energy during the fusion process. When heavier nuclei split apart into lighter nuclei, energy is also released in the fission process. The desire of an atomic nucleus to become more stable is what drives fission and fusion. Thus, the most stable nuclei will have a mass number of about 60, which explains why iron is the most stable element in the universe.
- The fusion of lighter-than-iron elements could release energy to create nuclei with higher binding energy (per nucleon).
- The energy released during the fission of elements heavier than iron may lead to the creation of nuclei with higher binding energies (per nucleon).
Particularly when merging tiny nuclei like hydrogen and helium into larger nuclei, nuclear fusion produces more energy than nuclear fission.
