Question

Explain the difference between nuclear fission and nuclear fusion.

Answer 1

Difference between nuclear fission and nuclear fusion are:

Nuclear fission:

1. In nuclear fission, a heavy nucleus splits up into lighter nuclei.
2. Harmful radiations are emitted in nuclear fission
3. It starts when slow neutrons bombard the heavy nucleus like uranium-235
4. It causes much pollution.
5. A large amount of energy is released in nuclear fission.
6. It can be controlled.

Nuclear fusion:

1. In nuclear fusion, two or more light nuclei combine to form a heavy nucleus.
2. No harmful radiations are emitted in nuclear fusion.
3. It starts when light nuclei are heated at very high temperatures.
4. It causes no pollution.
5. The energy released in nuclear fusion is much more than nuclear fission.
6. It can not be controlled.
