Element 115 is currently using Uup, the English abbreviation, which is highly radioactive and will decay into other elements in less than a second. In 2003, American and Russian researchers first discovered this element, but its existence has not yet been finalized.
Professor Dirk Rudolf of Lund University in Sweden and others reported that they used a calcium ion containing 20 protons to bombard a film containing 95 protons of strontium and re-synthesized element 115.
This finding once again proves the existence of element 115, but it has to wait for the International Union of Pure and Applied Chemistry (IUPAC) to obtain an official name and be included in the periodic table.
