$_{92}U^{238}$ emits $8$ $\alpha$-particles and $6$ $\beta$-particles. The neutron/proton ratio in the product nucleus is

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

The isotopic mass of ${}_{3}^{7}Li$ is $7.016005 \ u$ and those of the $H$ atom and neutron are respectively $1.007825 \ u$ and $1.008665 \ u$. Then,the binding energy of the ${}_{3}^{7}Li$ nucleus is: (in $MeV$)

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 $MeV$)

All the nuclei from the initial element to the final element constitute a series which is called

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