Tennessine Element in Periodic Table | Atomic Number Atomic Mass

Tennessine

Tennessine Element:

Tennessine is a radioactive chemical element. In April, 2010, Tennessine was created by the scientist at Joint Institute for Nuclear Research in Dubna, Russia, along with scientists from the U.S. Department of Energy's Lawrence Livermore National Laboratory and Oak Ridge National Laboratory. It has not been observed in nature. In the periodic table it is a p-block metallic element and it is a member of the 7th period and is placed in group 17. Its atomic number is 117 and symbol is Ts. Tennessine contains two isotopes with known half-lives and two with unknown half-lives. The most stable isotope is 294Ts, with a half-life of about 80 milliseconds.

Uses Of Tennessine Element:

  • Since only a few atoms of Tennessine have ever been made, at present Tennessine is used only in scientific research and it has no known biological role.
