The energy released in an atom bomb explosion is mainly due to

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

The hydrogen bomb is based on the phenomenon 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 the radioactive disintegration series ${}_{90}^{232}Th \rightarrow {}_{82}^{208}Pb$ involving $\alpha$ and $\beta$ decay,the total number of $\alpha$ and $\beta$ particles emitted are:

Statement $1$: The nuclide $_{13}^{30}Al$ is less stable than $_{20}^{40}Ca$. Statement $2$: Nuclides containing an odd number of neutrons are generally unstable.
