IUPAC (International Union of Pure and Applied Chemistry) on 28th November acknowledged the names and symbols of elements 113, 115, 117 and 118. Elements 113, 115, 117 and 118 will now be officially referred to as nihonium (Nh), Moscovium (Mc), tennessine (Ts) and Oganesson (Og).

These elements were originally announced to enter the periodic table by IUPAC back in January 2016 even though they had no name. While these elements were synthesized between 2002 and 2010 and officially recognized by the IUPAC in December of last year, IUPAC had initiated a waiting period for the names of these elements to come up before they enter the periodic table. In June, scientists and normal people were asked to submit names for the elements which was followed by a 5 month period in which h the public could also make suggestions or raise concerns about the element names. This was done in order to raise the awareness the new elements and it showed great results. The feedback from the public was great and many suggested names like Trumpium, after the U.S. President-elect Donald Trump and Octarine the “color of magic” from Terry Pratchett’s “Discworld” novels.

“Overall, it was a real pleasure to realize that so many people are interested in the naming of the new elements, including high-school students, making essays about possible names and telling how proud they were to have been able to participate in the discussions,”

Jan Reedijk, president of IUPAC’s inorganic chemistry division, said in the statement.

“It is a long process from initial discovery to the final naming, and IUPAC is thankful for the cooperation of everyone involved. For now, we can all cherish our periodic table completed down to the seventh row.”

The final decision for the names was naturally decided in a more diplomatic manner. The elements were name after their discoverers or inspired by a city and a state, respectively.

  • Nihonium was inspired by the Japanese word “nihon” for Japan.
  • Oganesson was named for Russian scientist Yuri Oganessian.
  • Moscovium (Moscow) and Tennessine (Tennessee), were named after a city and state.

The new elements will fill out the table’s seventh row, sporting the symbols Nh, Mc, Ts and Og.
