It is now official, four new elements have been added to the periodic table. This may be the event of a life time since the four new superheavy elements complete the seventh row of the periodic table.
The elements were named 113, 115, 117, and 118, meaning that new elements between hydrogen (having only one proton in its nucleus) and element 118 (having 118 protons) have been discovered.
These elements were known since end of 2015 as ununtrium (Uut), Uup (ununpentium), Uus (ununseptium) and Uuo (ununoctoium).
The discovery gave the scientists naming rights. Certain rules apply, since only five categories of names are allowed, namely:
- mythological concepts or character
- mineral or substance
- place or geographic region
- a property of the element
The names selected were announced in June 2016, namely Nihonium, Moscovium, Tennesine and Oganesson.
- Nihonium (Nh) – 113, since this element was discovered by scientists at the Riken Nishina Center for Accelerated Science in Japan
- Moscovium (Mc) – 115, since this element was discovered at the Joint Institute for Nuclear Research in Dubna, near Moscow
- Tennessine (Ts) – 117, since this name acknowledges scientific contributions from Tennessee, home of the Oak Ridge National Labatory, Vanderbilt University and the University of Tennessee at Knoxvile
- Oganesson (Og) – 118, since this element was discovered by collaborating teams of Russia in the city of Dubna and Americans at the Lawrence Livermore national Laboratory in California.
The names of these new superheavy, radioactive elements were for five years up for public comment.
