Atomic heraldry

Coat of arms of Fryazino, Russia showing an electron orbit

Atomic heraldry is heraldry characterised by the appearance of charges including the atom or showing the motion of parts of the atom; more loosely, it may describe heraldry in which atoms or the component parts thereof are represented through a combination of other charges. Obviously, this is a late development in heraldry.

The arms of Saint-Vulbas, Ain, France show "a sign of" the atom.

The arms of George Georgiou contain a representation of an atom with four electrons Sable in orbits Gules.[1]

There is an instance of a methane molecule in the arms of Hoerskool Secunda.[2]
