The volume occupied by an atom is greater then the volume of the nucleus by a factor of about
The fraction of volume occupied by the nucleus with respect to the total volume of an atom is
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
