Untriseptium (pron.: //), also known as element 137, is the temporary name of a hypothetical superheavy element in the periodic table that has the temporary symbol Uts and atomic number 137. As of 2016, no attempt has been made to synthesize untriseptium.
As of 2016, no attempt has been made to synthesize untriseptium.
Untriseptium is a temporary IUPAC systematic element name derived from the digits 137, where "un-" represents Latin unum meaning "one", "tri-" from tres meaning "three" and "sept-" from either Greek hepta or Latin septua, both meaning seven. Research scientists usually refer to the element simply as element 137. 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).
