Name of new element, tennessine, recognizes state’s contributions, including at ORNL

The recently discovered element 117 has been officially named “tennessine” in recognition of Tennessee’s contributions to its discovery, including the efforts of the U.S. Department of Energy’s Oak Ridge National Laboratory and its Tennessee collaborators at Vanderbilt University and the University of Tennessee.

“The presence of tennessine on the Periodic Table is an affirmation of our state’s standing in the international scientific community, including the facilities ORNL provides to that community as well as the knowledge and expertise of the laboratory’s scientists and technicians,” ORNL Director Thom Mason said in a press release.

The International Union of Pure and Applied Chemistry, or IUPAC, gave its final approval to the name “tennessine” following a year-long process that began December 30, 2015, when IUPAC and the International Union of Pure and Applied Physics announced verification of the existence of the superheavy element 117. That was more than five years after scientists first reported its discovery in April 2010.

IUPAC validates the existence of newly discovered elements and approves their official names.

ORNL had several roles in the discovery, the most prominent being production of the radioisotope berkelium-249 for the search. [Read more…]

Four new elements have been added to the periodic table, filling the seventh row, or period, and Oak Ridge National Laboratory played a role in discovering two of them.

The discovery and assignment of elements with atomic numbers 113, 115, 117, and 118 was announced on December 30 by the International Association of Pure and Applied Chemistry. The discoveries have been officially verified.

ORNL participated in the discovery of elements 115 and 117 in a collaboration between the Joint Institute for Nuclear Research in Dubna, Russia, and Lawrence Livermore National Laboratory in California.

The discoverers, who also include researchers in Japan, will now be invited to suggest permanent names and symbols.

For now, the elements are known as: [Read more…]
