Russia's successful synthesis of element 117 will be included in the periodic table of the elements
The Russian scientific research team recently successfully synthesized element 117 again, thus clearing the obstacles for the official addition of element 117 to the periodic table.
The Dubna Joint Nuclear Research Institute, headquartered outside the Russian capital Moscow, successfully synthesized element 117 for the first time in 2010. However, the International Union of Theoretical and Applied Chemistry (IUPAC) requires the Dubna Joint Nuclear Research Institute to synthesize the element again before they can formally approve its addition to the periodic table.
A senior person in charge of the Dubna Joint Nuclear Research Institute said that the research team has successfully completed the verification work and formally submitted an application for registration of element 117 to IUPAC; if successful, element 117 will be named within one year, And included in the periodic table of elements.
It is reported that the Dubna Joint Nuclear Research Institute used a particle cyclotron to bombard 249 atoms containing 97 protons and 152 neutrons with 48 atoms of calcium composed of 20 protons and 28 neutrons, resulting in 6 A new atom of 117 protons, 5 of which have 176 neutrons and the other atom has 177 neutrons.
The Mendeleev's periodic table of elements, which came out in 1869, is one of the basic laws of the universe. It also provides a ruler with precise scales for humans to understand nature. Among them, elements after element Uranium No. 92 do not exist in nature, and must be obtained by artificial synthesis. The Dubna Joint Nuclear Research Institute had previously successfully synthesized elements 113, 115, and 118. In addition, the German Federation of Helmholtz National Research Centers is working on the synthesis of elements 119 and 120.
