The usual definition of nuclear density gives for its density: Its radius of this nucleus will be:ДЄssuming it is spherical, its volume will be: Assuming spherical shape, nuclear radii can be calculated according to following formula:ДЇor example, natural uranium consists primarily of isotope 238U (99.28%), therefore the atomic mass of uranium element is close to the atomic mass of 238U isotope (238.03u). Typical nuclear radii are of the order 10 в€’14 m. The nuclear density for a typical nucleus can be approximately calculated from the size of the nucleus and from its mass. Since atomic nucleus carries most of atomвЂ™s mass and atomic nucleus is very small in comparison to entire atom, the nuclear density is very high. It is the ratio of mass per unit volume inside the nucleus. Nuclear density is the density of the nucleus of an atom. It is assumed they have densities of 3.7 Г— 10 17 to 6 Г— 10 17 kg/m 3, which is comparable to the approximate density of an atomic nucleus of 2.3 Г— 10 17 kg/m 3. They are so dense that one teaspoon of its material would have a mass over 5.5Г—10 12 kg. A nucleus is held together by the strong force, whileВ a neutron star is held together by gravitational force.Дensity of neutron star is enormous. But be careful, neutron stars and atomic nuclei are held together by different forces. Since they have some similar properties as atomic nuclei,В neutron stars are sometimes described as giant nuclei. It is believed that under the immense pressures of a collapsing massive stars going supernova it is possible for the electrons and protons to combine to form neutrons via electron capture, releasing a huge amount of neutrinos. A neutron star is basically a giant atomic nucleus about 11 km in diameter made especially of neutrons. Neutron stars are the smallest and densest stars known to exist and they are rotating extremely rapidly. The densest material found on earth is the metal osmium, but its density pales by comparison to the densities of exotic astronomical objects such as white dwarf stars and neutron stars.ДЄ neutron star is the collapsed core of a large star (usually of a red giant).
