Their addition completed the seventh row of the periodic table. Oganesson was named after Professor Yuri Oganessian for his work on superheavy elements.

The elements were given temporary names until the scientists who discovered them could pick suitable names.
Scientists from the schools, along with scientists from around the globe, combined forces to help discover a new super-heavy element, which will be called “Tennessine”.
The element with atomic number 115 has a proposed name of moscovium (symbol Mc), and for element 117, the name presented is tennessine (symbol Ts).
According to IUPAC rules, you can only name an element after five things: a scientist, a mythological concept or character, a mineral or similar substance, a place or a property of the element, like its color. They hailed from the Joint Institute for Nuclear Research in Dubna, Russia; Oak Ridge National Laboratory; Vanderbilt University, Lawrence Livermore National Laboratory, and the RIKEN Nishina Center for Accelerator-Based Science in Japan.
The name recognizes the contributions of Oak Ridge National Laboratory, the University of Tennessee and Vanderbilt University.
Vanderbilt physics professor Joseph Hamilton, who played a role in the discoveries, proposed naming an element for Tennessee. Over an 18-month period, ORNL’s produced and purified the target material (berkelium) that was used in an accelerator experiment at Russia’s Joint Institute for Nuclear Research to produce the new element.
Oganesson, discovered by collaborating teams at the Russian Joint Institute for Nuclear Research and US -based Lawrence Livermore National Laboratory, was named for professor Yuri Oganessian.
Element 113 is to be named nihonium (symbol Nh).

The public comment period will end November 8. “It is thrilling to recognise that global collaborations were at the core of these discoveries and these new names also make the discoveries somewhat tangible”.
