The naming ceremony for the chemical element tennessine took place at the Oak Ridge National Laboratory in Oak Ridge, Tennessee. Tennessine, a synthetic element with the atomic number 117, was officially recognized by the International Union of Pure and Applied Chemistry (IUPAC) in November 2016. The naming of the element was a tribute to the state of Tennessee, recognizing the vital contributions of local researchers in the field of nuclear science. The element was synthesized through collaborative efforts involving the Joint Institute for Nuclear Research in Dubna, Russia, and the Lawrence Livermore National Laboratory in California.

During the ceremony, notable figures from the scientific community, including members of the IUPAC, were present to celebrate this milestone. The event served not just as a celebration of scientific achievement, but also as a means to inspire the younger generation to pursue careers in STEM (science, technology, engineering, and mathematics). With the official name revealing the state's rich heritage in science and research, tennessine's designation aims to promote the scientific legacy of Tennessee.

The celebration included talks by leading chemists and nuclear physicists who discussed the element’s characteristics, its discovery process, and its significance in the periodic table. The ceremony highlighted how tennessine, being heavier than other elements, is unstable and radioactive, with a very short half-life. While its practical applications are limited due to its synthetic nature, the element plays an important role in understanding the behavior and properties of superheavy elements, contributing valuable data to the field of nuclear chemistry and physics.
