Nuclear density

Nuclear density is the density of the nucleus of an atom, averaging about 2.3×10 kg/m. The descriptive term nuclear density is also applied to situations where similarly high densities occur, such as within neutron stars.

The nuclear density for a typical nucleus can be approximately calculated from the size of the nucleus, which itself can be approximated based on the number of protons and neutrons in it. The radius of a typical nucleus, in terms of number of nucleons, is $R=A^{1/3}R_0$ where $A$ is the mass number and $R_0$ is 1.25 fm, with deviations of 0.2 fm from this value. The density of the nucleus is thus:
