For nuclear fusion reactions, the fusion temperature is of the order of

Who observed that when the nucleus of a uranium atom was bombarded with fast-moving neutrons,it became so unstable that it immediately broke into two nuclei of nearly equal mass,besides other fragments?

In a nuclear reactor,the chain reaction is controlled by introducing:

Nuclei tend to have more neutrons than protons at high mass numbers because

The end product of the $(4n + 2)$ radioactive disintegration series is:

$A$ nuclear reaction is accompanied by a loss of mass equivalent to $0.01864 \; amu$. The energy liberated is .......... $MeV$.
