Untritrium (pron.: /ntrˈtriəm/), also known as element 133, is the temporary name of a hypothetical superheavy element in the periodic table that has the temporary symbol Utt and atomic number 133. As of 2016, no attempt has been made to synthesize untritrium.

HistoryEdit

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

NamingEdit

Untritrium is a temporary IUPAC systematic element name derived from the digits 133, where "un-" represents Latin unum meaning "one" and "tri-" from tres meaning "three".[3] Research scientists usually refer to the element simply as element 133. 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).[4]
