History and Uses:
On February 2, 2004, scientists working at the Joint Institute for Nuclear Research in Dubna, Russia, along with scientists from the U.S. Department of Energy's Lawrence Livermore National Laboratory and Oak Ridge National Laboratory, announced the creation of moscovium. In experiments performed between July 14, 2003 and August 10, 2003, atoms of americium-243 were bombarded with ions of calcium-48 using a device called a cyclotron. This produced one atom of moscovium-287 and three atoms of moscovium-288. All four atoms quickly decayed into other elements.
Since only a few atoms of moscovium have ever been produced, it currently has no uses outside of basic scientific research.
