![]() At the height of the cold war, the Lawrence Berkeley Laboratory, US, and the Joint Institute of Nuclear Research in Russia tussled over who discovered elements 104, 105 and 106 and who should name them.īack in 1947, Iupac had introduced a set of recommendations to stop such a conflict arising. In the 1960s, Iupac got caught up in the transfermium wars. The naming of new elements hasn’t always been an apolitical event and the US and the USSR argued over this during the cold warīut it hasn’t always been plain sailing. The cyclotron at Berkeley National Laboratory. If they cannot come up with a name within six months, however, Iupac’s inorganic chemistry division will pick one for them. When there is a joint discovery, Iupac invites the groups to agree on a suggested name and symbol. In recent years, research groups have often worked together to produce a new element, as is the case for moscovium, tennessine and oganesson. What if two groups discover the same element – who names it then? After Iupac verify the result, only then are the superheavyweight hunters invited to suggest a name and symbol for their newly-discovered element. This is the organisation responsible for standardising weights, measures, element names and symbols. Once a group has found a new element, they submit their findings to the International Union of Pure and Applied Chemistry (Iupac). All four elements were formally recognised in January 2016. By 2006, a joint effort between the Joint Institute for Nuclear Research in Russia and the Lawrence Livermore National Lab, US, unearthed the elusive element. The result was retracted only two years later, however, as the lab couldn’t reproduce it. Scientists at Lawrence Berkeley National Laboratory, US, first claimed to have discovered oganesson – named in honour of nuclear physicist Yuri Oganessian – back in 1999. But not as long as oganesson (Og), element 118. Elements 115, named moscovium – after the region that the Russian Joint Institute for Nuclear Research is situated – and element 117, tennessine (Ts) – named in honour of the US state of Tennessee where Oak Ridge National Laboratory can be found – also took a long time to produce. In the case of element 113, now named nihonium in honour of Japan, it took the team at Riken eight years to get enough evidence to prove it existed. The most recent superheavyweights to be created are elements 113, 115, 117 and 118. ![]() If they’re lucky a new superheavy element is made – albeit one that’s in existence for a matter of seconds. Teams accelerate light nuclei – calcium-48 is a particular favourite – in a cyclotron, before firing the projectile at a target, such as bismuth. So, since the 1930s, scientists have tried to synthesise new ones via nuclear fusion. The majority of the periodic table contains elements found naturally on Earth – up to around atomic number 92, with a few exceptions. This will mean creating an element with over 100 protons in its nucleus, known as a superheavy element. How do you get the chance to name a new element?įirst things first, you’ve got to make a new element.
