$A$ deuteron is bombarded on an $_8O^{16}$ nucleus and an $\alpha$-particle is emitted. The product nucleus is

If the radius of a nucleus with atomic number $Z = 50$ is $9 \times 10^{-15} \ m$,what is the electric potential at its surface?

Which of the following is most unstable?

$A$ nucleus of deuterons or deuterium is a bound atomic system best described by

Consider the following two statements, $A$ and $B$ and identify the correct answer given below:
$A$. Nuclear density is same for all nuclei.
$B$. Radius of the nucleus $R$ and its mass number $A$ are related as $\sqrt{A} \propto R^{1 / 6}$.

The nuclides of $^{197}_{79} \text{Au}$ and $^{198}_{80} \text{Hg}$ are called . . . . . . of each other.
