What type of element is ununseptium?
It is a member of the halogen group. The element, No. 117 on the Periodic Table of Elements, had previously been designated ununseptium, a placeholder name that means one-one-seven in Latin. In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name tennessine for element 117.
Is ununseptium a man made element?
Ununseptium (also named eka-astatine or just element 117) is the superheavy (very heavy), manmade chemical element with a temporary symbol Uus and atomic number 117. It is the second-most heaviest element of all, and is the second-to-last element.
What are the uses of element 117?
At present, tennessine is only used for research. Scientists are investigating the properties of the element and using it to produce atoms of other elements through its decay scheme. There is no known or expected biological role of element 117.
Is ununseptium a metal?
An international team of scientists announced over the weekend that they confirmed the existence of the heaviest metal ever observed: element 117. The metal, which does not exist in nature, has become known as ‘ununseptium’ (Latin for 117), though no officially recognized name has yet been determined.

How was the element 117 discovered?
The existence of element 117 was deduced from the decay patterns observed after a radioactive berkelium target was bombarded with calcium ions at the JINR U400 cyclotron in Dubna.
