Seventh Row of Periodic Table Completed! Four New Elements
The discovery of four super-heavy chemical elements by scientists located in America, Russia and Japan has been verified by the experts and therefore formally added to the periodic table, competing the seventh row. Unfortunately it’s not good news for all as science textbooks around the world have immediately gone out of date.

The new elements are the first to be added to the table sine 2011, when elements 114 and 116 were added. The four new elements were verified on 30th December by the International Union of Pure and Applied Chemistry (IUPAC), who are based in the US, the global organisation that governs chemical nomenclature, terminology and measurement.
The IUPAC announced that a Russian-American team of scientists at the joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California, had given enough evidence to claim the discovery of elements 115,117 and 118.
Some elements on the periodic table have fairly wacky names, so how do they get them?
The teams responsible for the discoveries have been invited to come up with permanent names and chemical symbols for the now-confirmed elements. New elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist.
After the responsible IUPAC division accepts the new names and two-letter symbols, they will be presented for public review for five months.IUPAC awarded credit for the discovery of element 113 to a Japanese team at the Riken Institute. The chemistry organisation’s council will then make a final decision.
“The chemistry community is eager to see its most cherished table finally being completed down to the seventh row. IUPAC has now initiated the process of formalising names and symbols for these elements,” said Prof Jan Reedijk, president of the inorganic chemistry division of IUPAC.
