If ${}^{235}U$ is bombarded with neutrons,the atom will split into:

The highest binding energy per nucleon will be for

Which of the following is the most stable atom?

By which law is the energy produced in a nuclear reaction given?

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:

The number of neutrons in the parent nucleus which gives $^{14}N$ on $\beta$-emission is
