Unbitrium (pronounced /ənˈbɪtriəm/) is the temporary name of an undiscovered chemical element in the periodic table that has the temporary symbol Ubt and has the atomic number 123.
[edit] History
The name unbitrium is used as a placeholder, as in scientific articles about the search for element 123. Transuranic elements (those beyond uranium) are, except for microscopic quantities and except for plutonium, always artificially produced, and usually end up being named for a scientist or the location of a laboratory that does work in atomic physics (see systematic element name for more information).
[edit] Fictional Reference to Element 123: Jamesium (Rj)
In the fictional universe of Star Trek: The Next Generation, this element was apparently discovered and named. The episode "Rascals" depicted a "trans-periodic table," in a schoolroom set, which depicted element number 123 as being named jamesium, symbol Rj, having an atomic weight of 326. The graphic was created by set artists, probably a homage to designer Richard D. James, and listed this element in the fictional "gamma series."
