Magic number (chemistry)

  1. Gas laws

In case a gas condenses into clusters of atoms, the number of atoms in these clusters varies between a few and hundreds. However, there are peaks at specific sizes, usually one at lower and one at larger numbers. Often, specific numbers dominate. These numbers are called magic numbers, a term borrowed from the same concept in nuclear physics.

In this context, magic numbers often represent three-dimensional figurate numbers such as the octahedral numbers: they count the numbers of spheres in sphere packings of Platonic solids and related polyhedra.[1][2]
