Why is 117 called Ununseptium?
Ununseptium is called element 117 because it has 117 protons and 117 electrons. Elements with such a high number of protons are not found free in nature. The heaviest element that occurs in nature has 92 protons (uranium). Heavier elements are made in research settings by using nuclear reactions to add more protons.

In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name tennessine for element 117.
Why is Tennessine named after Tennessee?
The recently discovered element 117 has been officially named “tennessine” in recognition of Tennessee’s contributions to its discovery, including the efforts of the Department of Energy’s Oak Ridge National Laboratory and its Tennessee collaborators at Vanderbilt University and the University of Tennessee.
Why is it called Tennessine?
Hamilton initially proposed the name tennessine to honor the state where three of the participants – Vanderbilt, Oak Ridge and the University of Tennessee – are located. The name is spelled tennessine instead of tennessium because the new element is classified as a halogen-like chlorine and fluorine.
