4 new elements in the periodic table have been named by scientists

The International Union of Basic Chemistry and Applications (IUPAC) has added elements 113, 115, 117 and 118 to the periodic table earlier this year, which will be named nihonium (Nh), moscovium respectively (Mc), tennessine (Ts) and oganesson (Og).

These are just names proposed by scientists and must wait for the community's evaluation. In January 2016, IUPAC officially recognized the discoveries of groups of scientists from Japan, Russia and the United States, and filled the 7th cycle of the periodic table with four new elements. At that time, these elements had only temporary and difficult names, including: ununtri (UUT), ununpenti (Uup), ununsepti (UUS) and ununocti (Uuo).

As discoverers of the new element, the aforementioned group of scientists has been given naming rights, with very specific criteria.

Under IUPAC regulations, any new element must be named according to the following rules:

1. A concept or mythical character
2. A mineral or similar material
3. A place or geographic area
4. A property of the element
5. A scientist

Researchers at RIKEN Institute in Wako (Japan) have proposed the name nihonium (Symbol: Nh) for their discovery - element 113. Known in Japanese, Nihon is a term used to refer to "Japan." ".

Moscovium (Mc) and Tennessine (Ts) , names of elements 115 and 117 , were proposed by expert groups at the Nuclear Research Institute in Dubna (Russia), and Oak Ridge National Laboratory, University Vanderbilt and Lawrence Livermore National Laboratory (LLNL) in the United States. Moscovium is based on Moscow (Russia's capital) and Tennessine is located in Tennessee (a state of the United States).

Finally, the oganesson (Og) was proposed by the research team in Dubna and LLNL, after the name of Yuri Oganessian , a Russian physicist who had discovered the element 114 in 1999. Known elements 114 and 116, now known as flerovi and livermori, are the last elements to 'join' the periodic table, since 2011.

New names will undergo a 5-month period for the public to review, meaning that it is still possible to change at the last hour. Everything is expected to be completed by the end of this year. Meanwhile, the hunt for the first heavy elements, the first element of the 8th cycle, is still ongoing.
