“After Divisional acceptance, the names and two-letter symbols will be presented for public review for five months, before the highest body of IUPAC, the Council, will make a final decision on the names of these new chemical elements and their two-letter symbols and their introduction into the Periodic Table of the Elements, “concluded IUPAC in its statement”. “For over seven years”, Morita said, “we continued to search for data conclusively identifying element 113, but we just never saw another event”.

The International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics have recognised the discoveries of elements 113, 115, 117 and 118.
Elemental…Not only does Lemmy have a star named him, he also started his musical career in the “space-rock” band, Hawkwind. To date, element 118 is the heaviest element with 118 protons alongside 176 neutrons. All four are highly unstable superheavy metals that exist for only a fraction of a second. They followed up these experiments with more convincing evidence in 2012.
Sorry, college students. You will, in fact, need the newest edition of that chemistry textbook.
Elements 115 (ununpentium) and 117 (ununseptium) were discovered by groups collaborating across three institutions – Lawrence Livermore National Laboratory in the U.S., the Joint Institute for Nuclear Research in Russian Federation and Oak Ridge National Laboratory in the US. The discovery of these elements was no easy task, though. The new elements aren’t actually visible to scientists, but extrapolate the fleeting existence of the elements from their decay products.
The proposed names are then checked by the Inorganic Chemistry Division of IUPAC “for consistency, translatability into other languages, possible prior historic use for other cases, etc”. Element 113 will be the first symbol to named and discovered by an Asian researcher, reports Science News.

In a statement on their website, the president of IUPAC, Dr Mark C. Cesa said, “we are excited about these new elements, and we thank the dedicated scientists who discovered them for their painstaking work, as well the members of the IUPAC/ IUPAP Joint Working Party for completing their essential and critically important task”. With their positioning, the heretofore incomplete seventh row will get complete.
