The radius of atom is of the order of 1 A and radius of nucleus is of the order of fermi. How many magnitudes higher is the volume of atom as compared to the volume of nucleus ?

Explanation

Radius of atom `=1Å=10^(-10) m`
Radius of nucleus 1 fermi `=10^(-15) m`
Volume of atom `=V_(1)=(4)/(3) pi R_(2)^(3)`
`(V_(1))/(V_(2))=((4)/(3)piR_(1)^(3))/((4)/(3)pi R_(2)^(3))=((10^(-10))/(10^(-15)))=10^(15)`
