Final names for the new chemical elements

Something that affects me as a chemist and a terminologist has happened. I’m obviously not talking about my sprained wrist after falling off my bike, which forced me to write this post with only my right hand. Yes, that happened, but it affects me many additional parts of my life.

The IUPAC (International Union of Pure and Applied Chemistry) has officially validated the new names and symbols for the elements that remained unnamed in the seventh period (i.e. line) of the periodic table.

On the 8th of June, the IUPAC presented the names and symbols proposed by the teams that discovered the four elements. Although more about synthesising and characterising rather than discovering nowadays. Five months of revision were required, finishing on the 8th of November, for the IUPAC Council to formally approve them. Note that the approval was made public on the 30th; I’m not the only one with no rush to publish.

The new names and symbols

atomic number
name symbol
113 nihonium Nh
115 moscovium Mc
117 tennessine Ts
118 oganesson Og

The first three names are related to the places of the discovery of the elements. Nihon is a way of pronouncing in Japanese the name of Japan. Moscovium refers to Moscow, the capital city of Russia. And tennessine comes from Tennessee, in the USA. Oganesson, however, honours Yuri Oganessian for his contribution to transactinoid elements research.

Now you know what to call these four elements in your everyday conversations about chemistry. Or, at least, there are some new combinations of letters to obtain a high score playing Scrabble.
