The periodic table of the elements just got a new member. At least, maybe it did – it’s hard to tell. Having run out of new elements to discover, scientists have over the past several decades been making ‘synthetic’ atoms too bloated to exist in nature. But this is increasingly difficult as the atoms get bigger, and the new element recently claimed by a Japanese group – currently known simply as element 113, its serial order in the periodic table – is frustratingly elusive. These artificial elements are made and detected literally an atom at a time, and the researchers claim only to have made three atoms in total of element 113, all of which undergo radioactive decay almost instantly.

That, and competition from teams in the United States and Russia, makes the claim controversial. The first group to sight a new element enjoys the privilege of naming it, an added spur to the desire to be first. Just as in the golden years of natural-element discovery in the nineteenth century, element-naming tends to be nationalistic and chauvinistic. No one could begrudge Marie and Pierre Curie their polonium, the element they discovered in 1989 after painstakingly sifting tonnes of uranium ore, which they named after Marie’s homeland. But the recent naming of element 114 ‘flerovium’ – after the founder of the Russian institute where it was made – and element 116 ‘livermorium’, after the Lawrence Livermore National Laboratory where it originated, display rather more concern for bragging than for euphony.
