Chemistry · Structure of atom

If the radius of a nucleus of a heavy atom \( A \) is estimated, what is the approximate ratio of the nuclear radius to the radius of its atom if the atomic radius is of the order of \( 10^{-10}\text{ m} \) and nuclear radius is \( 10^{-14}\text{ m} \)?

1. A
   \( 10^{-4} \)
2. B
   \( 10^{-2} \)
3. C
   \( 10^{2} \)
4. D
   \( 10^{4} \)
