Four new chemical elements will take their places in the periodic table, the International Union of Pure and Applied Chemistry (IUPAC) announced last week. IUPAC verified the discoveries of elements 113, 115, 117, and 118, which complete the periodic table’s seventh row.
“The study, conducted this fall, focuses on developing new methods of synthesis for super heavy elements. The newly discovered, exotic nuclei are one isotope each of heavy elements berkelium, neptunium and uranium and two isotopes of the element americium. [..] Apart from discoveries themselves, the discovery is the first proof of the new technique for production of these exotic nuclides.” [From Phys.org ]
