V = volume of substance | in^3 | mm^3 |
Atomic number density, abbreviated as \eta (Greek symbol eta), is the number of atoms of a particular element per unit volume of a substance. It is a measure of how closely packed atoms are within a material. The atomic number represents the number of protons in the nucleus of an atom of that element. Therefore, the atomic number density is specific to a particular element and reflects how many atoms of that element are present in a given volume. Atomic number density is used in various scientific and engineering fields, such as materials science, physics, and chemistry, where understanding the distribution and arrangement of atoms within a material is essential for predicting its properties and behavior.
