Years after their discovery, the super-heavy elements 114 and 116 have finally been christened by their Russian and American discoverers. The elements have been named flerovium and livermoreium, also known as Fl and Lv. CREDIT: Lawrence Livermore National Labs
Chemistry's periodic table can now welcome livermorium and flerovium, two newly named elements, which were announced Thursday (Dec. 1) by the International Union of Pure and Applied Chemistry. The new names will undergo a five-month public comment period before the official paperwork gets processed and they show up on the table.
Three other new elements just recently finished this process, filling in the 110, 111 and 112 spots.
The periodic table of elements just got a bit heftier today (Nov. 4), as the names of three new elements were approved by the General Assembly of the International Union of Pure and Applied Physics.
Elements 110, 111 and 112 have been named darmstadtium (Ds), roentgenium (Rg) and copernicium (Cn).
All five of these elements are so large and unstable they can be made only in the lab, and they fall apart into other elements very quickly. Not much is known about these elements, since they aren't stable enough to do experiments on and are not found in nature. They are called "super heavy," or Transuranium, elements.
The newly named elements fit in the 114 and 116 spots, down in the lower-right corner of the periodic table, and were officially accepted to the periodic table back in June. They originally were synthesized more than 10 years ago, after which repeat experiments led to their confirmation.
