Four New Elements added to the Periodic Table

Chemistry Is Exciting!

The scientists who found them must now come up with formal names to replace the clunky Latin-based placeholders – ununtrium, ununpentium, ununseptium and ununoctium – which reflect their atomic numbers, 113, 115, 117, and 118. The atomic number is the number of protons found in an element’s atomic nucleus.
IUPAC announced that a Russian-American team of scientists at the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California had produced sufficient evidence to claim the discovery of elements 115, 117 and 118.
The body awarded credit for the discovery of element 113, which had also been claimed by the Russians and Americans, to a team of scientists from the Riken institute in Japan.
