Element Story - Tennessine

Tennessine is an element with atomic number 117, belonging to Group 17 of the periodic table as a superheavy element. All of its currently known isotopes are radioactive, it is not found in nature, and is synthesized artificially in particle accelerators. It was first synthesized in 2010 through a joint research effort between the Joint Institute for Nuclear Research in Dubna, Russia, and American research institutions. It was named in honor of the state of Tennessee in the US, which contributed to its discovery. Tennessine is not utilized in daily life or industry due to the extremely small number of atoms produced and its short half-life; it is primarily used to study the nuclear structure and radioactive decay of superheavy elements. Chemically, it is expected to exhibit properties related to other Group 17 elements like fluorine, chlorine, bromine, iodine, and astatine, but its very large atomic number means relativistic effects significantly influence its electron configuration. Therefore, research suggests it may possess stronger metallic properties and lower reactivity compared to other halogens.
