Ununoctium (element 118, symbol Uuo) has been created by a lab in Russia, as part of a joint U.S.-Russia project. They created three atoms of ununoctium-294 by colliding nuclei of californium-249 with nuclei of calcium-48:
I’ve already added it to my classroom periodic table:
- The creation of Uuo has been announced before. In 1999, a team of American scientists announced that they had synthesized this element, only to have other scientists pick their evidence apart.
- I haven’t seen this reported on news sites yet; I’m not sure why not. It is on the Wikipedia home page today, with the article on ununoctium giving more details. Being that anyone can edit a Wikipedia article, this left me a little sceptical until I found the news release from the Lawrence Livermore National Laboratory online.
- The name “ununoctium” is a temporary name meaning 1-1-8. It may take years for a decision to be made on its official name and symbol.
