Q.

The particle required to continue the chain process of Uranium fission is –

A. Electron
B. Proton
C. Neutron
D. Positron
Answer» C. Neutron
Explanation: Fission as encountered in the modern world is usually a deliberately produced man-made nuclear reaction induced by a neutron. The nuclear fuels undergo fission when struck by fission neutrons, and in turn emit neutrons when they break apart. This makes possible a self-sustaining nuclear chain reaction that releases energy at a controlled rate in a nuclear reactor or at a very rapid uncontrolled rate in a nuclear weapon.
