Question

Nuclear fission is the splitting of an atom and the process emits enormous amounts of energy. When uranium is bombarded by a neutron the reaction results in barium, krypton, three neutrons and energy. The three neutrons are produced in the reaction play a critical role in nuclear energy. Why is it necessary that each fission event produce more than one neutron to sustain the chain reaction discussed above? What role do these neutrons play in an atomic bomb? Please use more than 100 words.

Answer 1

Intensity of nuclear reaction should increase with time. SO more than 1 neutron needs to be produced by each reaction. The escaping neutrons that comes out as a product of neaclear reaction striked the surrounding uranium nuclei and thus fission more of the surrounding uranium nuclei, which then emit more neutrons that split still more nuclei. Thus it develops series of rapidly multiplying fissions and it leads to chain reaction in which nearly all the fissionable material is consumed, in the process generating the explosion of what is known as an atomic bomb.

Neutron hits the nucleus and causes instability which leads to fission
