Tennessine, a synthetic element with the symbol Ts and atomic number 117, is part of the halogen group in the periodic table. Its reactivity is expected to be quite high, similar to that of other halogens, but detailed experimental data on its reactivity are limited due to its short half-life and the challenges in producing sufficient quantities for extensive study.
As a halogen, tennessine is anticipated to exhibit reactivity patterns akin to those of other elements in its group, such as iodine, bromine, and chlorine. This means it may readily react with metals and other nonmetals, forming a variety of compounds. However, being a heavy element, its behavior could also show unique characteristics not seen in lighter halogens.
Furthermore, based on theoretical calculations and periodic trends, tennessine’s reactivity could be influenced by relativistic effects, which are significant for heavy elements. In practical terms, while we can make predictions about its reactivity, thorough experimental investigations would be necessary to fully understand its chemical behavior. Therefore, while we can assume tennessine is very reactive, conclusive data is still lacking.
