Atomic radius is to of the order of `10^(-8)` cm and nuclear radius is to order of `10^(-13)`cm. Calculate what fraction of atom is occupied by nucleus.

Explanation

Volume of nucleus `=(4)/(3)pir^(3)=(4)/(3)pi(10^-13)^(3)cm^(3)`
Volume of atom `=(4)/(3)pi(10^(-8))^(3) cm^(3)`, `V_(N)/V_("Atom")=10^(-39)/10^(-24)=10^(-15)`
`V_("Nucelus")=10^(-15)xxV_("Atom")`
