Periodic Table of Elements Makes Room for Two More

Say hello to Flerovium and Livermorium.

The International Union of Pure and Applied Chemistry officially approved names for the elements – which sit at slot 114 and 116, respectively — on May 31. They have until now gone by the temporary monikers ununquadium and ununhexium.

Both elements are man-made, having first been synthesized at the Joint Institute of Nuclear Research in Dubna, Russia, in 1998 and 2000.  The discoveries were confirmed with further work at Lawrence Livermore National Laboratory in California. Suggested names for the two elements have been pending since they were submitted to the IUPAC last year.

The elements were created by smashing calcium ions (with 20 protons) into curium targets (which have 96 protons), combining to form element 116, Livermorium. This element decayed almost immediately into Flerovium, with 114 protons.

And for that absolutely care, Flerovium’s symbol on the Periodic table will be ‘Fl’ and Livermorium’s will be ‘Lv’.
