The nucleus of an atom with an atomic mass of $24$ and atomic number $11$ consists of:

Let the binding energy per nucleon of a nucleus be denoted by $E_{bn}$ and the radius of the nucleus be denoted by $r$. If the mass numbers of nuclei $A$ and $B$ are $64$ and $125$ respectively, then:

Are the nucleons fundamental particles,or do they consist of still smaller parts? One way to find out is to probe a nucleon just as Rutherford probed an atom. What should be the kinetic energy of an electron for it to be able to probe a nucleon? Assume the diameter of a nucleon to be approximately $10^{-15} \ m$.

Which of the following pairs is an isobar?

The neutron was discovered by

$A$ nucleus of mass number $189$ splits into two nuclei having mass numbers $125$ and $64$. The ratio of the radii of the two daughter nuclei is:
