The atom bomb is based on the principle of:

Sulphur $-35$ $(34.96903 \ amu)$ emits a $\beta -$ particle but no $\gamma -$ rays,the product is chlorine $-35$ $(34.96885 \ amu)$. The maximum energy emitted by the $\beta -$ particle is (in $MeV$)

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

In the successive emission of $\alpha$- and $\beta$-particles,the number of $\alpha$- and $\beta$-particles that should be emitted for the conversion of ${}^{238}_{92}U$ to ${}^{206}_{82}Pb$ are:

If radium and chlorine combine to form radium chloride, the compound would be
