Untriunium (pron.: //), also known as element 131, is the temporary name of a hypothetical superheavy element in the periodic table that has the temporary symbol Utu and atomic number 131. As of 2016, no attempt has been made to synthesize untriunium.
As of 2016, no attempt has been made to synthesize untriunium.
Untriunium is a temporary IUPAC systematic element name derived from the digits 131, where "un-" represents Latin unum meaning "one" and "tri-" from tres meaning "three". Research scientists usually refer to the element simply as element 131. Transuranium elements like this usually end up being named after a scientist or the location of a laboratory that does work in atomic physics.
Atomic and physicalEdit
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).
