The actual process combines hydrogen nuclei ie protons to produce helium. Nuclear fusion occurs in the stars and accounts for all their energy output including that of our sun. In the case of nuclear fission an atom divides into two or smaller or lighter atoms.
Nuclear fission and fusion involve the disintegration and combination of the elemental nucleus. There are two types of nuclear reactions called nuclear fission and nuclear fusion. The harnessed nuclear energy is released in nuclear reactions.
Therefore in fission reaction a heavy nucleus of atom is bombarded so. Fission means to split and fusion means to combine. Nuclear fission and nuclear fusion are two types of nuclear reactions.
The reason fission occurs is that energy upsets the balance between the electrostatic repulsion between positively charged protons and the strong nuclear force that holds protons and neutrons together. Fission is a type of nuclear reaction that may occur spontaneously or as a result of a particle striking an atomic nucleus. Fission was discovered in 1938 by the german scientists otto hahn lise meitner and fritz strassmann who bombarded a sample of uranium with neutrons in an attempt to produce new elements with z 92.
Nuclear fission is the splitting of a heavy nucleus into two lighter ones. Nuclear fission and fusion. In both reactions the atoms are altered and the end products would be completely different from the initial reactants nuclear fusion releases a higher energy than that of nuclear fission.
These reactions release a very high amount of energy. Nuclear fusion and nuclear fission are chemical reactions that take place in the nucleus of an atom. Main difference nuclear fission vs fusion.
Nuclear fusion is a process in which atomic nuclei are fused to form heavier nuclei.
Nuclear fusion and fission examples. When the nuclei are merged the excess energy is released. Like fission nuclear fusion can also transmute one element into another. For example hydrogen nuclei fuse in stars to form the element helium fusion is also used to force together atomic nuclei to form the newest elements on the periodic table. Nuclear fission was first discovered by scientist otto hahn and fritz strassmann in 1938.
Nuclear fusion is the breakdown of a heavy nucleus into two lighter nuclei due to bombardment of neutron. Nuclear fission generates a lot of radioactive particles. Nuclear fission reactor is based on a concept of controlled fission chain reaction. Applications of nuclear fusion.
We are still at an experimental stage as far as nuclear fusion reactions are concerned. No combustion occurs in nuclear power fission or fusion so there is no air pollution. The fusion reactors will not produce high level nuclear wastes like their fission counterparts so disposal will be less of a problem. Nuclear fission can occur naturally as in the decay of radioactive isotopes or it can be forced to occur in a reactor or a weapon.
Example of nuclear fission. 235 92 u 1 0 n 90 38 sr 143 54 xe 3 1 0 n.
