Periodic Table's 7th Row Completed With Discovery Of Four New Elements

Officials from the International Union of Pure and Applied Chemistry (IUPAC) have confirmed the discovery of elements 113, 115, 117, and 118, announcing that there is now enough evidence to give them permanent places on the periodic table, which means they’ll also need new, official names.

You won’t find these four elements in nature - they are synthetic elements that can only be produced in the lab, and because they decay in a matter of seconds, their existence has been extremely difficult to confirm. Until now, elements 113, 115, 117, and 118 had temporary names and positions on the seventh row of the periodic table because scientists have struggled to create them more than once.

The three remaining elements, 115, 117, and 118 - known temporarily as ununpentium (Uup), ununseptium (Uus), and ununoctium (Uuo), respectively - will also get new names.

The organisation advises that the new elements can be named after a mythological concept, a mineral, a place or country, a property, or a scientist, and will be presented for public review for five months before a final decision about the new official name and symbol is made.
