Vedclass · Answer

(D) The radius of an atom is approximately $R_a = 10^{-10} \ m$.The radius of a nucleus is approximately $R_n = 10^{-15} \ m$.The volume of a sphere is given by $V = \frac{4}{3} \pi R^3$.Therefore,the ratio of the volume of the atom to the volume of the nucleus is:$\frac{V_a}{V_n} = \frac{\frac{4}{3} \pi (R_a)^3}{\frac{4}{3} \pi (R_n)^3} = \left( \frac{10^{-10}}{10^{-15}} \right)^3 = (10^5)^3 = 10^{15}$.Thus,the volume of an atom is about $10^{15}$ times larger than the volume of its nucleus.

The volume occupied by an atom is greater than the volume of the nucleus by a factor of about
