Untrihexium (pron.: /ntrˈhɛksiəm/), also known as element 136, is the temporary name of a hypothetical superheavy element in the periodic table that has the temporary symbol Uth and atomic number 136. As of 2016, no attempt has been made to synthesize untrihexium.

HistoryEdit

As of 2016, no attempt has been made to synthesize untrihexium.

NamingEdit

Untrihexium is a temporary IUPAC systematic element name derived from the digits 136, where "un-" represents Latin unum meaning "one", "tri-" from tres meaning "three"[3] and "hex-" from Greek hex meaning six.[4] Research scientists usually refer to the element simply as element 136. Transuranium elements like this usually end up being named after a scientist or the location of a laboratory that does work in atomic physics.

ChemicalEdit

Very little is known about the superactinides. Elements in this region are likely to be highly unstable with respect to radioactive decay, and have extremely short half lives (with the possible exception of element 126).[5]
