Four New Elements Finally Fill Up Seventh Row


News just in! It has been announced today that the seventh row of the period table has finally been filled up, with elements 113, 115, 117 and 118 being verified by the International Union of Pure and Applied Chemistry  (IUPAC) on 30 December.

The body announced that a team of Russian and American scientists had provided sufficient evidence for elements  115, 117 and 118 to be added to the periodic table, and IUPAC awarded credit for element 113 to a group of Japanese researchers at the Riken Institute.

The elements are the first to be added since 2011, when elements 114 and 116 were added.

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.”

IUPAC has now initiated the process of formalising names and symbols for these elements, temporarily named as ununtrium, (Uut or element 113), ununpentium (Uup, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118). The groups credited for proving the existence of the elements are currently thinking of names for the elements, which will then be present to IUPAC to go under public review.

Like other super-heavy elements, these elements are artifically made and only exist for very short periods of time before decaying into more stable elements.

The chemistry community is abuzz with this news, and I’m sure we’re all very excited to find out what names are given to the final members of Period 7!
