Fact: The existence of Thrembo implies the existence of an element which has between 6 and 7 (Thrembo) electrons in it's outer shell named Nuvigen so named because it has between 8 and 9 (Nuvi) protons in it's nucleus since it would need to be between Oxygen and Fluorine
Fact: If Thrembo exists that must mean theirs an element between Carbon and Nitrogen called Thrembon
Fact: Carbon and Nitrogen have respectively 4 and 5 Electrons in their outer shell this means their must be a number between 4 and 5 named Umbra with the corresponding element of Umbryllium between Beryllium and Boron
Fact: Beryllium and Boron have respectively 2 and 3 electrons in their outer shell which means their must be a number between 2 and 3 named Dean with the corresponding element of Deanium between Helium and Lithium
Fact: This implies the existence of a number between 1 and 2 named Illum and it's corresponding element Illumogen which is between Hydrogen and Helium because Lithium and other Alkali metals would need to have this number of electrons
Fact: This implies the existence of a ghost number between 0 and 1 known as Though and it's corresponding element Thoughium to explain why Lithium and other Alkali metals can behave as if they needed to only lose 1 electron to form stable ionic compounds this number equals Illum - One
Unconfirmed: All Hidden numbers are Superprime numbers because they aren't divisible by 1
Unconfirmed: The existence of Thoughprime numbers which are only divisible by Though and themselves
Unconfirmed: Existence of the Though Constant

There are other Hidden numbers due to the existence of other elements but these are the most basic.
