Show that the volume of nucleus is proportional to its atomic mass number.
The ratio of radii of nuclei $_{13}A{l^{27}}$ and $_{52}{X^A}$ is $3 : 5$. The number of neutrons in the nuclei of $X$ will be
If radius of the $^{27}_{13}Al$ nucleus is taken to be $R_{Al}$, then the radius of $^{125}_{53}Te$ nucleus is nearly
Of the following pairs of species which one will have the same electronic configuration for both members?
Explain by illustrating the types of atoms.
What percentage of the mass of the nucleus is the mass of the nucleus ?
