New Elements Added to Periodic Table

Periodic TableThe seventh row of the period table has been completed with the addition of four new elements. The International Union of Pure and Applied Chemistry (IUPC) has officially filled slots 113, 115, 117, and 118 with the tentatively ununtrium, ununpentium, ununseptium, and ununoctium.

These are the first new elements to be officially added to the period table since felrovium and livermorium in 2011.
