Write the relation of the size of the nucleus to the atomic size.
Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$
Assertion $A:$ The binding energy per nucleon is practically independent of the atomic number for nuclei of mass number in the range $30$ to $170$.
Reason $R$ : Nuclear force is short ranged.
In the light of the above statements, choose the correct answer from the options given below on
Isotopes are atoms having
Give a general introduction to the nucleus.
Highly energetic electrons are bombarded on a target of an element containing $30$ neutrons. The ratio of radii of nucleus to that of Helium nucleus is ${14^{1/3}}$. The atomic number of nucleus will be
