Notes

Element 113 is the first to be discovered in an Asian country. The researchers proposed the name nihonium to celebrate it. "Nihon" is one of two ways to say "Japan" in Japanese, and means "Land of Rising Sun." The element was discovered by a team at RIKEN Nishina Center for Accelerator-Based Science and led by professor Kosuke Morita.

The researchers said their search for element 113 began by "bombarding a thin layer of bismuth with zinc ions traveling at about 10% the speed of light." By doing so, they would theoretically fuse, forming an atom of element 113.
A Russian-American team at the Joint Institute for Nuclear Research in Dubna, Russia, and at Oak Ridge National Laboratory in Tennessee and Lawrence Livermore National Laboratory in California discovered elements 115, 117 and 118.
Both moscovium and tennessine honor where they were discovered: Moscow and Tennessee, respectively. Researchers used the Dubna Gas-Filled Recoil Separator at the Joint Institute for Nuclear Research along with the heavy ion accelerator capabilities at the Flerov Laboratory of Nuclear Reactions in Moscow. For tennessine, researchers at the Oak Ridge National Laboratory, Vanderbilt University and the University of Tennessee at Knoxville worked together on superheavy element research and synthesis using Oak Ridge's High Flux Isotope Reactor and Radiochemical Engineering Development Center.

Oganesson, discovered by collaborating teams at the Russian Joint Institute for Nuclear Research and U.S.-based Lawrence Livermore National Laboratory, was named for professor Yuri Oganessian. The scientist, born in 1933, was a pioneer with achievements including the discovery of superheavy elements.
