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

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.

The name unbihexium is a temporary IUPAC systematic element name.

History

The name unbihexium is used as a placeholder, such as in scientific articles about the search for element 126. Transuranic elements beyond plutonium are 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.

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