The ratio of the volume occupied by an atom to the volume of the nucleus is 

Answer:

Explanation:

As we knows, radius of an atom, 

$\gamma_{A}\approx 10^{-10}m$

 radius of nucleus,   $\gamma_{B}\approx 10^{-15}m$

 So, ratio of their volumes

$\frac{V_{A}}{V_{N}}=\frac{\frac{4}{3}\pi r^{3}_{A}}{\frac{4}{3}\pi r^{3}_{N}}=\left(\frac{r_{A}}{I_{N}}\right)^{3}=\left(\frac{10^{-10}}{10^{-15}}\right)^{3}$

 $V_{A}:V_{N}=10^{15}:1$
