Why is the density of a nucleus much more than that of the atoms?

Answer:

                The nuclear size is of the order of \[\text{1}{{0}^{-}}^{\text{14}}\text{m}\] and atomic size is of the order of \[\text{1}{{0}^{-}}^{\text{10}}\text{m}\]. So atomic size is \[\text{1}{{0}^{\text{4}}}\] times the nuclear size while atomic mass is slightly greater than nuclear mass due to the presence of electrons. Hence nuclear density is much greater than atomic density.
