Thuon

Thuons are elementary particles which are distant cousins of electrons. They are an optional particle that can be used to create atoms. Atoms with thuons in their composition are referred to as thuonic atoms, and have a thuonic shell that extends out 1,000× the distance of the electron shell. Thuons can change the properties of atoms, and originate new elements. They are most commonly represented with the Icelandic / Old English letter Thorn (þ), which is used for the "th" sound.

Geometry Warping

Thuonic elements regularly have some geometry-warping properties, such as spherical, hyperbolic or other geometries. These effects are normally very subtle, but get more noticeable when the concentration of thuons increases.

Thuon Stars

This is one of the most extreme cases of the geometry warping capability of thuons. These stars are made almost exclusively of thuons, and get their energy from thuon collisions:

Thuon collisions happen when two thuons meet each other at high speeds, and it releases a Primordium Sigma particle, a positron, and some energy.

Thuon Stars aren't actually spheres as the way we think of them, but hyperbolic holospheres, which means they are infinite planes.

Thuonic Elements

Thuonic elements have various peculiar properties. Here are a list of some of them, in order of discovery.

The symbols of thuonic elements always have "þ-" preceding it, which allows symbols from already existing elements to be used (such as Uranium's U or Phosphorus's P).

Name	Etymology	Symbol	Electron number	Thuon number	Rarity (parts per trillion)	Picture	Properties
Unobtanium	Means "not obtainable" Un-: negation un-obtain-ium: not obtainable element	þ-U	116	7	100	Nanopicture of an unobtanium crystal.	Has an insane durability (being a 26 on the Mohs Scale). Has a hyperbolic crystal pattern. Despite its hardness, can be dissolved using cuandaic acid.
Pulvigen	Means "generates dust" Pulvi-: dust -gen: Generates pulvi-gen: generates dust	þ-P	4	1	2.4 million	Pulvigen rock in a vacuum.	Opposite of unobtanium - turns instantly into tiny grains when exposed to any gas, including air, only being able to survive in big chunks in a vacuum. However, its alloys are insanely strong, almost that of unobtanium.
