Discovery of four super-heavy chemical elements by scientists in Russia, America and Japan has been verified by experts and formally added to table

Four new components have been added to the periodic table, eventually completing the tables seventh row and rendering science textbooks around the world instantaneously out of date.

The components, discovered by scientists in Japan, Russia and America, are the first to be added to the table since 2011, when components 114 and 116 were added.

The four were verified on 30 December by the US-based International Union of Pure and Applied Chemistry, the global organisation that governs chemical nomenclature, nomenclature and measurement.

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 produced sufficient evidence to claim the discovery of components 115, 117 and 118.

The body awarded credit for the discovery of component 113, which had also been claimed by the Russians and Americans, to a team of scientists from the Riken institute in Japan.

Kosuke Morita, who was leading the research at Riken, said his squad now planned to look to the unchartered province of component 119 and beyond.

Ryoji Noyori, former Riken president and Nobel laureate in chemistry said: To scientists, this is of greater value than an Olympic gold medal.

The components, which currently bear placeholder names, will be officially named by the teams that detected them in the coming months. Element 113 will be the first component to be named in Asia.

The chemistry community is eager to see its most cherished table eventually being completed down to the seventh row, said Professor Jan Reedijk, president of the Inorganic Chemistry Division of IUPAC.

IUPAC has now initiated the process of formalising names and emblems for these elements temporarily named as ununtrium,( Uut or element 113 ), ununpentium( Uup, element 115 ), ununseptium( Uus, element 117 ), and ununoctium( Uuo, element 118 ).

New components can be named after a mythological conception, a mineral, a place or country, a property or a scientist.

The four new components, all of which are man-made, were discovered by slamming lighter nucleu into each other and tracking the following decay of the radioactive superheavy elements.

Like other superheavy components that inhabit the end of the periodic table, they only exist for fractions of a second before decaying into other elements.
