According to Russian media reports on June 25, the Russian scientific research team successfully synthesized the 117 element again, which cleared the obstacle for the official addition of the 117 element to the periodic table.
The Dubna Joint Nuclear Research Institute, headquartered in Moscow, Russia, successfully synthesized the 117 element for the first time in 2010. However, the International Union of Theoretical and Applied Chemistry (IUPAC) required the Dubna Joint Nuclear Research Institute to re-synthesize the element before they could formally approve it to be added to the periodic table.
A senior director of the Dubna Joint Nuclear Research Institute said that the research team has successfully completed the verification work and officially submitted the registration application for element 117 to IUPAC; if successful, element 117 will be named within one year. And into the periodic table of elements.
It is reported that the Dubna Joint Nuclear Research Institute uses a particle cyclotron to bombard 锫249 atoms containing 97 protons and 152 neutrons with 48 atoms of 20 protons and 28 neutrons, resulting in 6 possessions. A new atom of 117 protons, five of which have 176 neutrons and the other have 177 neutrons.
The Mendeleev periodic table, which was introduced in 1869, is one of the basic laws of the universe, and it also provides a scaled precision ruler for human understanding of nature. Among them, the element after the elemental uranium No. 92 does not exist in nature, and must be obtained by artificial synthesis. The Dubna Joint Nuclear Research Institute has also successfully synthesized elements 113, 115 and 118. In addition, the Helmholtz National Research Center Federation in Germany is working on the synthesis of elements 119 and 120.
