Ununtrium is a chemical element with the symbol Uut and atomic number 113. It is a synthetic element that was first discovered in 2003 by a team of Russian and American scientists. As is common with newly discovered elements, ununtrium has a few synonyms that are used interchangeably. These include eka-thallium, element 113, and Uuq, the temporary element symbol given to the element prior to its official naming. Ununtrium is a highly reactive metal with potential applications in nuclear energy and medicine. Despite its relatively recent discovery, researchers around the world are studying this element to better understand its unique properties and potential uses.
