Tennessine

Part of speech: noun

Definitions

  1. A synthetic element with the symbol Ts and atomic number 117 ; first discovered in 2010 by Russian and American scientists working collaboratively
  2. Representing element 117, known as Ts ; named tennessine in honor of contributions from the state of Tennessee
  3. Classified as a superheavy element, Ts with atomic number 117 ; notable for being one of the few named after a U.S. state and predicted to be highly radioactive and extremely short-lived

Etymology: The element tennessine, with the atomic number 117, is one of the heaviest elements on the periodic table and belongs to the group known as the halogens. Its name is a tribute to the U.S. state of Tennessee, reflecting the significant contributions of scientific institutions located there, notably Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee. The choice of this name highlights the collaborative effort in the discovery and research of superheavy elements. Tennessine was first synthesized in 2010 by a joint Russian-American team at the Joint Institute for Nuclear Research in Dubna, Russia. The naming convention for new elements often honors places or people connected to the discovery, and in this case, Tennessee's role in nuclear science was commemorated. The element's symbol, Ts, follows the standard two-letter format assigned by the International Union of Pure and Applied Chemistry (IUPAC). The suffix "-ine" at the end of the name situates tennessine within the halogen family, which includes familiar elements such as chlorine, bromine, and iodine. This suffix has roots in Latin and Greek, traditionally used to denote elements in this group because of their chemical similarities. The adoption of a place name combined with this classical suffix underlines both the element’s chemical identity and its geographical significance. As a synthetic element, tennessine does not occur naturally and must be created in particle accelerators through fusion reactions involving lighter nuclei. Its discovery and naming represent the ongoing human quest to explore the limits of the periodic table, blending cutting-edge physics with a nod to regional pride in scientific achievement.
