Untrihexium (pronounced /ˌʌntraɪˈhɛksiəm/) is an unsynthesized chemical element with atomic number 136 and symbol Uth.
The name untrihexium is a temporary IUPAC systematic element name.
[edit] History
The name untrihexium is used as a placeholder, as in scientific articles about the search for element 136. 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).
