$A$ possible material for use in nuclear reactors as a fuel is

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 the decay,${}_Z^AX \to {}_{6}^{12}C + {}_{+1}^{0}\beta$,identify the values of $A$ and $Z$.

When a slow neutron goes sufficiently close to a ${^{235}U}$ nucleus,then the process which takes place is

Which atomic species cannot be used as a nuclear fuel?

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:
