Tennessine is the newest element on the periodic table. It was produced in 2011, at the Joint Institute for Nuclear Research (JINR), Dubná, Russia. The element is named after the U.S. state of Tennessee, home of the Oak Ridge National Laboratory, which housed one of the first large-scale nuclear reactors ever built. Only a few atoms of this halogen group element have been made. Even so, scientists have predicted that it will be a semi-metal, not a non-metal like the other halogens.
