Nuclear fission
Nuclear fission-
The process of splitting of a heavy nucleus into two lighter nuclie of a comparable masses (after bombardment with energetic particle) with liberation of energy.
For example, on bombarding a uranium target, the nucleus broke into two nearly equal fragments and released a great amount of energy -
Fission does not always produce Barium and Krypton. Here is another example:
All the fragmented nuclei produced in fission are neutron-rich and unstable. Also, they are radioactive and emit beta articles until they reach a stable end-product. So under favourable conditions, the neutron produced can cause further fission of other nuclie, producing large number of neutrons, Thus a chain of nuclear fissions is established which continues untill the whole Uranium is consumed.
