The ratio of the mass of an object to its volume. This calculation produce a quantity called electron density, a number that tells us the relative probability of finding an electron at a particular point in space. A measure of how tightly the matter in a substance is packed together.

Such immense densities are also found in neutron stars. The descriptive term nuclear density is also applied to situations where similarly high densities occur, such as within neutron stars.

What is density In other words, the density () of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that. Thus, the density of nuclear material is more than 2.10 14 times greater than that of water. A measure of how tightly the matter in a substance is packed together. Ρ nucleus = m / V = 238 x 1.66 x 10 -27 / (1.73 x 10 -42) = 2.3 x 10 17 kg/m 3. Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). The usual definition of nuclear density gives for its density: ![]() Its radius of this nucleus will be:Īssuming it is spherical, its volume will be: In other words, Energy Density can be defined as. Assuming spherical shape, nuclear radii can be calculated according to following formula:įor 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). Energy density is the quantity of energy that can be held in a given system, material, or region of space. Typical nuclear radii are of the order 10 −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 atom’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. ![]()
