Radius of the nucleus is about 105 times less than the radius of the atom.
The nucleus of an atom can be assumed to be spherical. The radius of the nucleus of mass number A is given by 1.25×10−13×A13 Radius of atom is one A . If the mass number is 64, then the fraction of the atomic volume that is occupied by the nucleus is
