Ununtrium (symbol Uut, atomic number 113) is a chemical element with a temporary name which was discovered in 2003 at the Lawrence Livermore National Laboratory and the Joint Institute for Nuclear Research.
Properties and Radioactive Isotopes
Ununtrium is predicted to share some properties with elements such as Thallium, Indium, Gallium, Aluminum, and Boron. However, it is expected to behave like a post-transition metal. This is the heaviest element in the boron group and the elements are also known as icosagens. Uut has an atomic weight of 286 and is solid at room temperature. Scientists predict a density of 16 grams...Read More
