Confirmation of the discoveries of and name proposals for elements 114 (flerovium) and 116 (livermorium)
element 114: Flerovium (Fl) after the physicist Georgiy Flerov. Georgiy N. Flerov (1913-1990) was a renowned physicist who discovered the spontaneous fission of uranium and was a pioneer in heavy-ion physics.
element 116: Livermorium (Lv), after the Livermore laboratories. A group of researchers from the Laboratory, along with scientists at the Flerov Laboratory of Nuclear Reactions, participated in the work carried out in Dubna on the synthesis of superheavy elements, including element 116.
