Question

Write any two differences between nuclear fission and nuclear fusion.

Hint:

Nuclear fission splits heavy nuclei, while nuclear fusion combines light nuclei. Fusion releases more energy than fission.

Answer 1

Nuclear fission and nuclear fusion are two different nuclear reactions that release energy due to high-powered atomic interactions. Below are the differences between nuclear fission and nuclear fusion:
1. Process: - **Nuclear Fission:** It is the process where a heavy nucleus, like uranium or plutonium, splits into two smaller nuclei along with the release of a large amount of energy. - **Nuclear Fusion:** It is the process where two light atomic nuclei, such as hydrogen isotopes, combine to form a heavier nucleus, releasing energy in the process.
2. Energy Yield: - **Nuclear Fission:** Fission reactions release a considerable amount of energy and are currently used in nuclear power plants. - **Nuclear Fusion:** Fusion reactions release far more energy per unit of mass than fission and are the source of energy in stars, including the sun.
