The periodic table adds two super heavy elements

The International Association for Basic Chemistry and Applications (IUPAC) has just announced a periodic table of chemical elements (welcoming the BTNT) to welcome two new super heavy elements and consider the workers' names for them as Flerovium (Fl ) and Livermorium (Lv).

>>>Add 3 new elements in the periodic table

The names of the two new elements need to be reviewed by the scientific community within 5 months before being officially included in the periodic table as the latest elements. Previously, the three super-energetic elements 110, 111 and 112 received respectively the elemental names Darmstadtium (Ds), Roentgenium (Rg) and Copernicium (Cn) and added to the periodic table.

According to LiveScience , two super-heavy elements Flerovium (Fl) and Livermorium (Lv) will occupy boxes 114 and 116, respectively, in the periodic table. The invention of both elements 114 and 116 involved different levels of scientists at the Lawrence Livermore National Laboratory and the Dubna JINR Nuclear Research Union Institute (Russia). And on June 1, 2011, the IUPAC made an official conclusion: The authors of the Dubna-Livermore experiment met copyright criteria for inventing new superheavy elements 114 and 116. And the authors The above is invited to propose names for elements 114 and 116 to approve the IUPAC General Assembly.

Initially, the research team Dubna, according to JINR Deputy General Director, expected the element 114 to be named flerovium (Fl) to commemorate physicist Georgy Flerov, while element 116 was named moscovium to honor Moscow Region. where there is Dubna city. But then it 116 was renamed livermorium (Lv) to honor the city of Livermore, where the Lawrence Livermore National Laboratory was located.

Element 114 was named after Russian physicist Gregory Flerov, former director and founder of the Nuclear Reaction Laboratory (named Flerov) of the Dubna Nuclear Research Institute (Russia). ). This is the famous nuclear physicist of the former Soviet Union and the world, making important contributions to the development of the Soviet nuclear weapons.

'Proposing names for two elements 114 and 116 not only honors the contributions of individual scientists in the field of nuclear science but also honors the cooperation among scientists in the two laboratories'. , Dr. Bill Goldstein, director of the Lawrence Livermore Laboratory, said.

According to PV (July 12, 2011, author TT Minh), "International research team Dubna-Livermore in recent years has actively hunted other super heavy elements at 113, 115, 117, 118. and, in turn, announced the results, however, until now, the latest products and new elements have not yet passed through the strict eyes of experts in the Joint Working Committee ( Joint Working Party of the International Association of Basic Chemistry and Applications (IUPAC) The above committee still recommends: The results obtained on the above elements 113, 115, 117 and 118 (and the results Other research by German scientists at GSI and Japan at RIKEN) has not yet met the criteria to recognize patent rights for its authors.
