Ununtrium 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.
History
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. Their discovery of the element still awaits confirmation. [1]
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. See Element naming controversy, systematic element name.
