Distinguish between nuclear fission and nuclear fusion?
Fission is the splitting of the nucleus of a large heavy atom such as uranium into two smaller parts. Fusion is the sticking together of two light nuclei to make a heavier one, as occurs in the stars. Both processes release energy.
The difference between Fusion and Fission is that Fission is easier to do and produces more energy than fusion reactions. However fission can be dangerous and is used in Nuclear reactors. Fusion however is safer and produces less energy but safely. It is quite difficult to cause a Fusion reaction however.
Nuclear fission and nuclear fusion are similar in that they both involve changes in the nucleus of the atom. Another similarity is that relatively high energies (for the size of the matter involved) are associated with those nuclear changes. In general, nuclear fission is the "splitting" of the nucleus of an atom, and nuclear fusion is the fusing or combining of two smaller atomic nuclei to form a larger one. Both nuclear fission and nuclear…
Nuclear fission is the splitting of heavy nuclei (as U-235) when bombarded by neutrons. The nuclear fusion is the combination of light nuclei into heavier nuclei. Both the nuclear fission and nuclear fusion result in loss of mass (or mass defect) that transforms into energy according to formula E = mc2 (c is light velocity).
Nuclear fission releases heat energy by splitting atoms. The word fission means a splitting or breaking up into parts. Nuclear fusion refers to the union of atomic nuclei to form heavier nuclei resulting in the release of enormous amount of energy. The word fusion means merging of separate elements into a unified whole.
