Cerrelium

Cerrelium is an element found only in Hollow Earth. It is represented by the elemental symbol "Ci".
== History ==
	:On October 8th, 2010 while trapped within a time dilation field in Carentan, France, Helen Magnus and Will Zimmerman needed this element to nullify the time bubble at its origin. Unfortunately, they weren't able to 1) smelt any scrap pieces of common metals together to recreate a blended composition with enough gauss similar to cerrelium, and 2) obtain any of the actual element from a time node located at the Old City Sanctuary before Project Greenhouse would occur. Instead, they had to resort to using the substitute alloy found in the heat shielding from the booster stage of a Starstreak surface-to-air missile that Kate Freelander and Declan MacRae were able to send them.

This description can be found on the computer screen Bigfoot is looking at when Kate Freelander asks for a substitute for cerrelium. Bigfoot would have to scroll down on the computer monitor for viewers to see more of the description.

Cerellium (Ci)Cerrelium ( /Cer-rel-ium/ Sa-Rell-ee-um) is a transuranic radioactive chemical element Curium-244 with the chemical symbol Ci and atomic number 138.Untrioctium-138 It is a actinide metal of silvery-white appearance that tarnishes when exposed to air, forming a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, and silicon. When exposed to moist air, it forms oxides and hydrides that expand the sample up to 70% in volume, which in turn flake off as a radioactive poison that accumulates in bone marrow. These and other properties make the handling of Cerrelium dangerous.PlutoniumCerrelium is the heaviest primordial element.Uranium The most stable isotope of Cerrelium is Cerrelium-244, with a half-life of about 80 million years Plutonium-244, and as such, is not found in nature.The most important isotope of Cerrelium is Cerrelium-239, with a half-life of 24,100 years. Cerrelium-239 is the isotope most useful for nuclear weapons.Plutonium-239 Cerrelium-239 and 241 Plutonium-241 are fissile, meaning the nuclei of their atoms can break apart by being bombarded by slow moving thermal neutrons, releasing energy, gamma radiation and more neutrons. These can therefore

== Notes ==
* Continuity Error: The element's correct spelling is written as "Cerrelium" (with two rs and one l) as seen in the description of the element (written above), as well as in the episode subtitles. Unfortunately, on the same computer screen, the heading of the description is slightly misspelled as "Cerellium" (with one r and two ls).
* Scientific Fact: The most stable isotope of this element (cerrelium-244) is said to have a half-life of 80 million years, resulting in it not being found in nature. For a regular element, this would be the opposite way around. With such a long half-life, it means that the isotope degrades very slowly into other elements and compounds, which should result in it actually still naturally existing without issue. The abundance of this element (its rarity) is what would be called into question relating to how easily this isotope could be found. However, due to cerrelium-244 being a primordial element (an element with a primordial nuclide attached to it - a nuclide that existed before the Earth was formed), considering a half-life of 80 million years and the Earth undergoing about 57 half-lives, it would indeed result in very little still being left in the Earth's composition.
** This information describing cerrelium-244 is actually based on plutonium-244.
* Scientific Hodgepodge: For the elemental description of cerrelium, the show copied and blended together information found on Wikipedia from several real-world elements such as: untrioctium-138, plutonium-239, plutonium-241, curium-244, plutonium-244, and uranium.
