Difference between nuclear fission and fusion? |
| Answer» \tNuclear FissionNuclear FusionWhen the nucleus of an atom splits into lighter nuclei through a nuclear reaction the process is termed nuclear fission.Nuclear fusion is a reaction through which two or more light nuclei collide with each other to form a heavier nucleus.When each atom split, a tremendous amount of energy is releasedThe energy released during nuclear fusion is several times greater than the energy released during nuclear fusion.Fission reactions do not occur in nature naturallyFusion reactions occur in stars and the sunLittle energy is needed to split an atom in a fission reactionHigh energy is needed to bring fuse two or more atoms together in a fusion reactionAtomic bomb works on the principle of nuclear fissionHydrogen bomb works on the principle of a nuclear fusion bomb.\t | |
