Tennessine is a superheavy synthetic chemical element with the chemical symbol Ts and atomic number 117. It is the second-heaviest element known to exist and the penultimate element of the 7th period of the periodic table. It is sometimes referred to as eka-astatine or element 117. Six tennessine atoms were seen during the initial 2010 syntheses, seven in 2012, and two in 2014. As of 2016, fifteen tennessine atoms have been seen.

The element's previous name, ununseptium, which translates to "one-one-seven" in Latin, was assigned to it when it was No. 117 on the Periodic Table of Elements.
What is Uus?
Uus is believed to be a super heavy element ever found on the earth with atomic number 117. It is not a naturally occurring element and radioactive and highly unstable. Presently, the use of Ts or Uus is not much but only limited to research work. Only a few atoms of Uus have been discovered to date and have metallic nature placed among halogens.
The element with atomic number 117 has the shorthand electron configuration $[Rn]$5f¹⁴6d¹⁰7s²7p5⁵.

Discovery of Tennessine
Tennessine was created through the fusion of element 20 with element 97, namely calcium-48 and berkelium-249. ²⁴⁹Bk with ⁴⁸Ca.
Scientists from the Joint Institute for Nuclear Research in Dubna, Russia, and the Lawrence Livermore National Laboratory in California discovered element 117 in 2010, and they jointly announced the discovery on April 5 of that year.
Their discoverers suggested names for elements 115 and 117. Both the names of the elements—moscovium and tennessine in the honor of the locals where the research that led to their creation was conducted.
Properties of Tennessine
Tennessine is predicted to have chemical characteristics of the halogens as a result of its placement in Group 17 of the periodic table. However, partial metalloid characteristics may occur from the impact of relativistic electrons.
Two isotopes of Tennessee have known half-lives, while the other two have unknown half-lives. The isotope 294Ts, with a half-life of roughly 80 milliseconds, is the most stable. It deteriorates via alpha decay. The other isotopes of tennessine are thought to undergo spontaneous fission as well as alpha decay.
The longest-living isotope is used to determine the atomic weight of transuranium elements created by humans. Since a new isotope with a longer half-life could be created in the future, these atomic weights should be regarded as tentative.
Uses of Tennessine
Tennessine has never been used for anything beyond fundamental research because so few atoms have ever been made.
Ununseptium is a recently discovered element with two of its isotopes. One of the isotopes has an atomic mass of 293, and another is having 294. However, the nature of both of them is highly unstable. Considering this element’s half-life, 293 isotope life is 14 ms, and 294 isotope life is 78 ms.
How did Ts Get Discovery?
It takes years to discover this element. However, the group of Russian and American scientists succeeded with it by bombarding two different elements- berkelium-249 and ions of calcium-48.
What are the Health aspects of Uus?
To date, only research is the primary purpose to study the Ts element. There is no particular use in daily life. Due to its radioactive nature, Uus is highly harmful to human health. However, there is no proper research done to date to know about its several health uses.
Key Properties of Ts
There is not much discovery on Ts, but still, there are some listed properties below:
It is highly radioactive and unstable.
It is placed among halogens as it is expected to show some related properties to them.
Relativistic electrons present in this element show some properties of being a metalloid.
Talking about the uses and application of Uus, there are such discoveries made to date. It is considered to be a synthetic chemical element with the 7th period.
Interesting Facts About Tennessine
It is the last element in the seventh period of the periodic table and the second-heaviest known element.
Element 117 has no known or anticipated biological function. Because it is radioactive and heavy, it is anticipated to be harmful.
Tennessine is currently only employed in academic settings. The element's decay mechanism is being used by scientists to create atoms of other elements as well as to study the features of the substance.
The chemical element Tennessine has the atomic number 117 and is a superheavy radioactive element. Tennessine is expected to be halogen as its position in the periodic table is in the 17th group. It is anticipated to be solid at room temperature.
Its uses are very limited as it is only synthesized for research purposes. Tennessine has two stable isotopes with Tennessine-294, the most stable isotope, having a half-life period of roughly 80 milliseconds. Moscovium-290 is produced as a result of alpha decay.
A biological function for element 117 is neither known nor anticipated. As a result of its radioactivity and weight, it is anticipated to be poisonous.
