Show that the volume of nucleus is proportional to its atomic mass number.
Two spherical nuclei have mass numbers $216$ and $64$ with their radii $R_1$ and $R _2$ respectively. The ratio, $\frac{R_1}{R_2}$ is equal to
The radius of germanium $(Ge)$ nuclide is measured to be twice the radius of ${}_4^9Be$ . The number of nucleons in $Ge$ are
If the nuclear force between two protons, two neutrons and between proton and neutron is denoted by $F _{p p}, F _{n n}$ and $F _{p n}$ respectively, then
In a nuclear reaction, which of the following is conserved
If the mass number of an atom is $A = 40$ and its electron configuration is $1{s^2},\;2{s^2},\;2{p^6},\;3{s^2},\;3{p^6}$, the number of neutrons and protons in its nucleus will be
