The names of the elements that were earlier proposed by the discoverers have been approved by the IUPAC

Chemistry textbooks are now just got a little heavier, as four new elements have been officially added to the periodic table.

On Wednesday, chemistry’s highest gatekeeper International Union of Pure and Applied Chemistry (IUPAC) has approved earlier proposed names for the four newly-discovered elements, which were formally known by their respective atomic numbers 113, 115, 117 and 118. 

Nihonium (Nh),' Moscovium (Mc), Oganesson (Og) and Tennessine (Ts) now join the elusive list of elements which is now expanded to 118 elements. This addition completes the seventh row of the periodic table.

The elements and their official names are:

Element 113: nihonium (Nh)

Element 115: moscovium (Mc)

Element 117: tennessine (Ts)

Element 118: oganesson (Og)

Nihonium or element 113 is the first to be discovered in Asia. All the other originated from west. Nihonium has been named after Japan (nihon) which is a way to say ‘Japan’ in Japanese and literally means the “the Land of Rising Sun.” 118 Oganesson has been named after scientist Yuri Oganessian for his pioneering research on superheavy elements, while 115 Moscovium and 117 Tennessine honor the areas of Moscow and Tennessee respectively where these elements have been discovered.

“The names of the new elements reflect the realities of our present time,” IUPAC President Prof Natalia Tarasova said in a statement.

All four new elements are not found in nature, and are synthetically created in laboratories. After the discovery process, researchers proposed a permanent name and symbol for the elements June this year. According to the IUPAC rules, new elements can be named after a mineral, a place or country, a property or a scientist. 

Once the proposed names are submitted, they were opened for public review for a five month period. After the completion of this review period, the organization has now made its final decision.

“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,” said Jan Reedijk, president of the Inorganic Chemistry Division of the IUPAC. “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.”
