Tennessine (Ts) is an artificially synthesized element with the atomic number 117. the properties of tennessine are still not fully characterized due to its extremely short half-life and the difficulty in producing enough of it for extensive study.
Based on its position in the periodic table, tennessine is expected to belong to the halogen group, which includes elements such as fluorine, chlorine, and iodine. Halogens are typically nonmetals. However, due to its position in the periodic table and its expected electronic configuration, there is speculation that tennessine may exhibit some metallic properties or behave as a metalloid.
It is important to note that without sufficient experimental data, it is challenging to definitively classify tennessine as a metal, nonmetal, or metalloid. Ongoing research and further experimentation are necessary to determine its precise characteristics and classification.
Please keep in mind that there may have been new developments in tennessine research .
