  Ununtrium - Wikipedia, the free encyclopedia
Ununtrium (eka-thallium) is the temporary name of an unconfirmed synthetic element in the periodic table that has the temporary symbol Uut and has the atomic number 113.
On February 1, 2004, ununtrium and ununpentium were reported by a team composed of Russian scientists at Dubna (Joint Institute for Nuclear Research), and American scientists at the Lawrence Livermore National Laboratory.

 ununtrium on Encyclopedia.com
Situated in group IIIa of the periodic table, it is expected to have properties similar to those of thallium and indium.
Among the products of the bombardment were four atoms of ununpentium (element 115), which in less than one tenth of a second decayed into atoms of ununtrium by emitting an alpha particle.
Two isotopes of ununtrium were identified, the longer-lived (Uut-284) having a half-life of about 48 millisecondsc, and the other (Uut-283) a half-life of about 46.6 milliseconds.

 Ununtrium
Ununtrium is the temporary name of an undiscovered chemical element in the periodic table that has the temporary symbol Uut and has the atomic number 113.
The name Ununtrium is used as a placeholder, such as in scientific articles about the search for Element 113; it is a Latinate way of saying "one-one-three-ium" ("ium" being a standard ending for element names).
Such transuranic elements are always artificially produced, and usually end up being named for a scientist.

 Team synthetically creates two elements
The new elements, temporarily named ununtrium and ununpentium, were formed from the collision of calcium and americium, two elements found in nearly everyone's household kitchen.
The discovery of ununtrium, element number 113 and ununpentium, element number 115, was made by a team of researchers from the Glenn T. Seaborg Institute and the Chemical Biology and Nuclear Science Division at the Lawrence Livermore Nationals Laboratory, along with colleagues from the Joint Institute for Nuclear Research in Dubna, Russia.
This is the first time these elements have been synthetically created, but scientists are still debating if they can exist in supernovas or during a process such as the Big-Bang.
