Unbitrium
In the fictional universe of Star Trek: The Next Generation, this element was seemingly 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."
