[Translation by Dr. Nachmani Moshe]
Following a previous announcement by the International Union of Pure and Applied Chemistry (IUPAC) regarding the acceptance of the demand for recognition of the four new elements, the self-discovering researchers were invited to propose names for the elements, and these are now published for public discussion with their final approval:
- Nihonium and its corresponding symbol Nh, for element 113
- Muscobium and its corresponding symbol Mc, for element 115
- Tensin and its corresponding symbol Ts, for element 117
- Ogenson and its corresponding symbol Og, for the element 118
The Division of Inorganic Chemistry of the International Union of Pure and Applied Chemistry (IUPAC) reviewed and considered these proposals for names and recommended their acceptance. The proposals themselves are directed to public comments for a period of five months, before the official and final approval that will be carried out by the union's council.
The instructions about naming new elements were passed on to researchers in order to help them choose appropriate names. A newly discovered element can be named based on: a) a mythological idea or personality (including celestial bodies); b) a mineral or similar substance; c) place or geographical area; d) property of the element; e) the name of a scientist. The names of new elements will usually have a suffix that reflects and preserves historical and chemical consistency: the suffix "ium" ("-ium") for elements belonging to groups 16-1, "-ine" ("-ine") for elements from group 17 and "on" (“-on”) for elements from group 18. And finally, the English names of the new elements will be such that they can be easily translated into the other most spoken languages.
For the element with atomic number 113, the researchers from Japan (RIKEN Nishina Center for Accelerator-Based Science) who discovered it proposed the name nihonium and the symbol Nh. Nihon is one of the ways to say "Japan" in Japanese, and the meaning of the name is "land of the rising sun". The name is proposed to create a direct connection to the country where the new element was discovered. Element 113 is the first element discovered on the continent of Asia. This proposal also honors the pioneering Japanese researcher Masataka Ogawa, who in 1908 helped discover element 43. The team also hopes that the pride in the discovery and the confidence in science that follows it will alleviate a little the sense of loss of confidence of the victims and their families who suffered greatly from the nuclear disaster in Fukushima.
For the element with atomic number 115, the researchers who discovered it proposed the name moscovium and the symbol Mc, and for the element with atomic number 117, the name tennessine and the symbol Ts. These names correspond to the recognition of a place or geographic region and were jointly proposed by their discoverers from Russia (Joint Institute for Nuclear Research, Dubna) and the USA (Oak Ridge National Laboratory, Vanderbilt University, Lawrence Livermore National Laboratory). The name Muscovium is a tribute to the contribution of the Moscow region where the researchers who discovered the element worked. The name Tensin is a tribute to the contribution of the Tennessee region in the USA, including Oak Ridge National Laboratory, Vanderbilt University in Nashville and the University of Tennessee in Knoxville for the study of the superheavy elements, including the chemical separation of unique target materials from actinides for the synthesis of the elements.
For the element with atomic number 118, the joint team of researchers from Russia (Joint Institute for Nuclear Research, Dubna) and the US (Lawrence Livermore National Laboratory) who discovered it proposed the name oganesson and the symbol Og. The proposal is in keeping with the tradition of honoring a scientist and thereby honors Professor Yuri Ogansyan for his pioneering contribution to the study of the elements beyond the actanide group. His many achievements include the discovery of superheavy elements and the significant progress in the field of atomic physics of superheavy nuclei, including obtaining experimental evidence for the existence of the concept of "an island of stability".
"It is a real pleasure to see that specific places and names (country, city and scientist) associated with the new foundations receive recognition within these four foundations. Despite the fact that these elections may be perceived by some people as self-satisfaction, the names do meet the requirements and conditions as established by the union," said one of its officials. At the end of the process, and after the end of the comment period on behalf of the general public, the final recommendations will be published in the official journal of the International Union of Pure and Applied Chemistry. Along with this announcement, other laboratories around the world are already focusing on the search for new elements in the eighth row of the periodic table, while trying to confirm the identification of the element Copernicium (atomic number 112) and other heavy elements.

What is the next stable element?
I wonder how they were created. A hypothesis using super massive lasers that produce temperatures of tens of millions of degrees in a small pin head. I will read online. Waiting for your article once on the topic of programming materials using nanotechnology. You had touches on the subject. The topic is hot today in electro-optics and any other field that applies physics that previously existed only in exotic places.
what is their life time Around that atomic number without the pressure present in the cores of massive stars, these elements disintegrate. The question is how long. Another interesting thing is why in area 93 they start to become unstable radioactive and decay.
