Dikironium (symbol Dk, and also known as copernicium or Cn) is a chemical element, atomic number 112on the periodic table.

Characteristics and history[]

Dikironium, in its most stable form, has an atomic mass of 300. Federation knowledge of this element's synthesis was based on the discovery of this substance by Vulcans for the first time in planet Vulcan's year 8810. This metal is part of the trans-uranic series of heavy elements. (ST reference: Star Fleet Medical Reference Manual)

Dikironium could only be created inside a laboratory and was not believed to exist naturally. This was disproved in 2257 and 2268, when the crews of the USS Farragut and the USS Enterprise discovered that the dikironium cloud creature was partly composed of the element. (TOS episode: "Obsession"; TOS - My Brother's Keeper novel: Constitution; TOS novel: The Ashes of Eden)

In real-life science, element 112 has only recently been discovered, and named "copernicium" (Cn). Like the reference in its Star Trek appearance, modern science has stated that this element cannot exist in nature without the application of special physics that applied to the cloud creature.
