Four new elements have been added to the periodic table, finally completing the table’s seventh row and rendering science textbooks around the world instantly out of date.
The elements, discovered by scientists in Japan, Russia and America, are the first to be added to the table since 2011, when elements 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, terminology 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 elements 115, 117 and 118.
The body awarded credit for the discovery of element 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 team now planned to “look to the unchartered territory of element 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”.
