About Tennessine
Tennessine has the symbol Ts and atomic number 117, which means every tennessine atom has 117 protons in its nucleus and, in a neutral atom, 117 electrons. At room temperature it is unknown (too few atoms have been made).
Only a few atoms of this element have ever been made, in particle accelerators, so most of its properties are predicted rather than measured.
