Tennessine is an element in the game. She used to be named Ununseptium.
"This is ununseptium and it was produced in Russia as late as 2009. As the discovery of this element has not yet been verified by IUPAC, its place in the Periodic Table is still unofficial.
How did they find it then? By bombarding berkelium with over 7 trillion calcium-48 ions per second for 70 days, all accelerated to 10% of the speed of light! Wow, quite an experiment!"
