The binding energy of $_8O^{16}$ is $127 \ MeV$. Its binding energy per nucleon is ...... $MeV$.

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

Starting from radium,the radioactive disintegration process terminates when the following is obtained:

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

If the mass defect of a nuclide is $3.32 \times 10^{-26} \ g$, its binding energy in $MeV$ is:

If the binding energy per nucleon of $_1H^2$ is $x$ and that of $_2He^4$ is $7x$,then the ratio of the energy liberated in the reaction $_1H^2 + _1H^2 \to _2He^4$ to the binding energy per nucleon of $_1H^2$ is:
