Unbihexium



Unbihexium is an unsynthesized chemical element with atomic number 126 and symbol Ubh. It is of interest because it is in the hypothesized island of stability.

Stable Unbihexium
Calculating by the Hartree-Fock-Bogoliubov Method using the non-relativistic Skyrme energy density, it could be possibly the most stable, in a "well" of stability, or island of stability, for Ubh-310.

Trivia
An Action Comics story by John Byrne established the fictional Kryptonite as element 126 on the periodic table of the elements.

The science fiction short story "Silence is Golden" by American science fiction author Lou Antonelli is based on the supposed discovery of Element 126 in a Texas open-pit mine. The story, published by Revolution Science Fiction in August 2003, received an Honorable Mention in "The Year's Best Science Fiction, 21st annual collection" (St. Martin's Press, New York, N.Y. Gardner Dozois, ed. 2004).
