Your Periodic Table Is Officially Out of Date

Gizmodo reports Your Periodic Table Is Officially Out of Date

Scientists with the International Union of Pure and Applied Chemistry (IUPAC) have officially approved the names of four new elements, completing the seventh row of the periodic table.

The four elements, discovered between 2002 and 2010, aren’t new per se, but the names are. IUPAC officially recognized the discovery of the super-heavy, highly reactive elements in December of 2015, and announced the suggested names back in June of this year. After a five-month chill-out period for the world to digest the new monikers, the bureau made the names official this week.

• Nihonium and symbol Nh, for the element 113
• Moscovium and symbol Mc, for the element 115
• Tennessine and symbol Ts, for the element 117
• Oganesson and symbol Og, for the element 118

Japanese researchers proposed Nihonium, which means Japan, and a team of scientists from Russia and the US named Moscovium for Moscow and Tennessine for Tennessee. Oganesson was named in honor of Yuri Oganessian, a Russian chemist. The additions replace the current seventh row placeholders, ununtrium, ununpentium, ununseptium, ununoctium (and good riddance)."
