What will be the ratio of radii of two nuclei with mass number A1 and A2?
The radius of nucleus of an atom of mass number A is given by R = R0A1/3 where R0 is unique constant = 1.2 x 10-15 m.
Hence , R α A1/3
So , ratio of radii of two nuclei with mass numbers A1 and A2 is R1/R2 = { A1/A2 }1/3
Hence , R α A1/3
So , ratio of radii of two nuclei with mass numbers A1 and A2 is R1/R2 = { A1/A2 }1/3
