🚨🚨 New element alert! 🚨🚨
Four new elements have officially been added to the periodic table of elements, according to the International Union of Pure and Applied Chemistry (IUPAC).
These elements had been going by their temporary names: ununtrium (113), ununpentium (115), ununseptium (117), and ununoctium (118).
Element 113 was confirmed by a Japanese research group. The other three were confirmed by a joint American-Russian effort.
It's one thing to find evidence of an element once. But to confirm its existence, as was done here, you need to demonstrate it experimentally multiple times.
