Element number 114 is now officially known as flerovium (symbol F1), after the Flerov Laboratory of Nuclear Reactions in Russia.
The elements were created at the Flerov lab in Dubna, Russia, in 1998 (flerovium) and 2000 (livermorium) by hurling calcium ions, with 20 protons each, into a piece of curium, which has 96 protons.
