Nuclear fission
. Splitting of a heavy nucleus into two or more lighter
nuclei.
e.g : 92U + 0n
235 1
56
Ba141 + 36 Kr92 + 3 0n1 + 200Mev
NUCLEI
. Uncontrolled chain reaction: principle of atomic bank. Nuclear
. Contralled chain reation: principle of nuclear reactors.
Nuclear of an atom onsists of proton and
Nuclear Fission neutrons collectively called nucleons.
