Let's Get to Know the Tennessine Element

Tennessine is the 117th element in the periodic table. The periodic table groups the elements according to their atomic numbers. The number of protons in the nucleus of the atom is known as the atomic number. Tennessi's atomic number is 117. The symbol “Ts” indicates that it belongs to Group 17 and Period 7 of the periodic table of elements. The US state of Tennessee, where Oak Ridge National Laboratory (ORNL) is located, inspired the name Tennessine.

The Joint Institute of Nuclear Research (JINR), Lawrence Livermore National Laboratory (LLNL) and Oak Ridge National Laboratory Tennesseeine (ORNL) collaborated on the discovery. The target substance, berkelium, was created at ORNL, which produced 22 milligrams in 250 days. The berkelium was then transported to the Atomic Reactors Research Institute (RIAR), where a 300 nm thin coating was deposited on a titanium plate. It was later moved to JINR and placed in the particle accelerator there. Calcium-48 was used to bombard the target and the data of the experiment was transferred to LLNL for processing. In 2010, the discovery was confirmed.

Tennessine was discovered in Dubna, Russia, by a Russian-American partnership in April 2010, and is the last element discovered as of 2022. In 2011, one of the daughter isotopes was produced directly, partially confirming the experiment's findings. The experiment was successfully rerun in 2012 by the same team, and in May 2014 by a joint German-American team. The element was accepted by the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP) Joint Working Group, which evaluated claims for the discovery of new elements, and priority was given to the Russian-American team.

Tennessine can be found on the "island of stability," a theory that explains why some superheavy elements are more stable than the rest of the periodic table, which shows a general trend toward decreasing stability. Tens to hundreds of milliseconds have passed since the Tennessin atoms were formed. Tennessine is estimated to belong to group 17 of the periodic table, all other elements of which are halogens. Due to relativistic effects, some of their properties may differ greatly from halogens. Therefore, tennessine is expected to be a volatile metal that does not form anion or reach high oxidation states.
