What's in a name? Named for the state of Tennessee.

Say what? Tennessine is pronounced as TEN-ess-een.

History and Uses:

On April 5, 2010, 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 tennessine. They produced tennessine by bombarding atoms of berkelium-249 with ions of calcium-48.

Tennessine's most stable isotope, tennessine-294, has a half-life of about 80 milliseconds. It decays into moscovium-290 through alpha decay.

Since only a few atoms of tennessine have ever been produced, it currently has no uses outside of basic scientific research.
