Explanation / Answer

the density of the nucleus of an atom is called as nuclear density it is the ratio of mass per unit volume which is inside the nucleus.The nuclear density of any nucleus can be approximately determined by the size of the nucleus, which can be calculated on the number of protons and neutrons.

mathematically nuclear density is given by n=3A/(4piR3) where A is mass number R is radius.

when the core of star begins to collapse, the density increases to a point where it becomes vigrously beneficial for electrons to be taken by protons thus produces neutrons and neutrinos. In this it changes the core of the star into neutrons & creates a extremely large burst of neutrinos. When this collapse reaches nuclear density, the star bounce back in an explosive manner, throwing its mass like elements.. This expansion by explosion is known as supernova supernova.

therefore in core when When densities reach nuclear density neutron degeneracy pressure halts the contraction.
