New Elements!!!

On Decemeber 30 2015, the International Union of Pure and Applied Chemistry (IUPAC) announced the discovery of 4 new elements. However, they weren’t given a name yet. On June 8th, IUPAC announced the names of the new elements.

  • Nihonium and symbol Nh, for the element 113.
  • Moscovium and symbol Mc, for the element 115.
  • Tennessine and symbol Ts, for the element 117.
  • Oganesson and symbol Og, for the element 118.

These elements will fill the 4 empty spaces 7th row of the periodic table. adjustedperiodictable

Naming rights usually go to the discoverer of the element.

For element 113, the discoverers at the RIKEN Nishina Center for Acceraltor Based Center (Japan) proposed the name nihonium to make a connection to the nation where it was discovered. Nihon in Japanese means “Japan” or “Land of the Rising Sun”. This element is the first to have been discovered in an Asian country.

Both element 115 and element 117 are honoring a place or geographical region. For element 115, the proposed name is moscovium (Moscov) and for element 117 it is tennessine (Tennessee). These elements are proposed jointly by the discoverers at the Joint Institute for Nuclear Research, Dubna (Russia), Oak Ridge National Laboratory (USA), Vanderbilt University (USA) and Lawrence Livermore National Laboratory (USA). In Moscov, the discovery experiments were conducted using the Dubna Gas-Filled Recoil Seperator and a heavy ion accelerator.

Finally for element 118, the teams at the Joint Institute for Nuclear Research proposed the name oganesson. This proposal is to honorate Professor Yuri Oganessian (1933~present) for his contriubutions to element research.

The elements are still proposals and are in the process of being approved. The final results will be announced on Novemeber 8th -then the results will be official.
