Atomic Number Density

 

Atomic Number Density Formula

\eta \;=\; \dfrac{  N }{ V }     (Atomic Number Density)

N \;=\;  \eta \cdot V 

V \;=\;  \dfrac{ N  }{ \eta }

Symbol English Metric
\eta   (Greek symbol eta) = atomic number density  atoms \;/\; in^3  atoms \;/\; mm^3
N = total number of atoms of the element dimensionless dimensionless
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.
