Haslam visits ORNL to highlight state’s role in discovering tennessine

Tennessee Governor Bill Haslam visited the U.S. Department of Energy’s Oak Ridge National Laboratory on Friday to congratulate the ORNL team involved in the discovery of the element tennessine, named in recognition of the vital contributions of the state of Tennessee to the international search for new superheavy elements.

UT-Battelle, the managing contractor of ORNL, is marking the discovery by providing more than 1,000 public middle schools and high schools in Tennessee with new charts of the periodic table. Tennessine—the official name for element 117—completes the seventh row of the table and the column of elements classified as halogens.

The charts will include the signatures of Haslam and ORNL Director Thom Mason.

“We had two very significant announcements in Tennessee this fall as it relates to science,” Haslam said. “In October, the Nation’s Report Card announced that Tennessee students are the fastest improving in the nation in science, and in November, Tennessee became only the second state to be recognized in the periodic table of elements. Having an element named in our honor is further evidence of the scientific excellence that exists at Oak Ridge National Laboratory, the University of Tennessee, Vanderbilt University, and other institutions throughout our state, and by UT-Battelle donating new periodic tables to every middle and high school in Tennessee, students can feel proud of our state’s important role in the scientific community and inspired to play a role in its future.” [Read more…]

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…]

Recognizing Tennessee’s contribution, Tennessine could be name of new chemical element

Tennessine is among the names proposed for four new elements. If approved, the name would recognize the contributions of Tennessee research centers—Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee—in the discovery of one of four new superheavy elements: 113, 115, 117, and 118.

Tennessine (Ts) is proposed for element 117.

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

Twenty-two milligrams of a very pure synthetic material produced at ORNL were used in the discovery of two of the new chemical elements. [Read more…]

Jim Roberto, an associate laboratory director at Oak Ridge National Laboratory, will discuss the discovery of elements 115 and 117, super-heavy nuclei, and the “island of stability” during a Wednesday evening talk next week.

Roberto, ORNL associate laboratory director for science and technology partnerships, will give the featured talk to the ORION astronomy club at 7 p.m. Wednesday, March 16. The talk will be at the Grove Theater at 123 Randolph Road in Oak Ridge.

Roberto’s talk is titled “The Discovery of Elements 115 and 117: SuperHeavy Nuclei and the ‘Island of Stability.'” Roberto will review recent progress in super-heavy element research with particular focus on the significance of element 117 and its decay products as evidence for the existence of the presumed “island of stability” for super-heavy nuclei, a press release said.
