Q.

Name the particle that is most essential to continue the chain reaction during the fission of uranium -

A. Electron
B. Proton
C. Neutron
D. Positron
Answer» C. Neutron
Explanation: Nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays), and releasing a very large amount of energy, even bythe energetic standards of radioactive decay. Fission as encountered in the modern world is usually a deliberately produced manmade nuclear reaction induced by a neutron.
