Russian physicists have synthesized two new elements

In the periodic table, you may receive the item named in honor of the Moscow region, told the vice-director of the Joint Institute for Nuclear Research (JINR) Mikhail Itkis.

According to him, shortly elements 116 and 114, previously synthesized in the institute, will be officially recognized by the International Union of Pure and Applied Chemistry (IUPAC). After that, Russian scientists will be able to formally invite the union name for these items.

In accordance with the rules of the IUPAC any discovery of a new element should be certified either in the same experiment in another laboratory or by another independent method. After receiving the confirmation, the application enters the IUPAC which confirms the discovery, the scientists have the right to propose a name for it.

"We would like to element 114 be named after Georgi Flerov — Flerov, and the second — Muscovy, not in honor of Moscow, and in honor of the Moscow region", — said Itkis. In turn, the director of the Laboratory of Nuclear Reactions Sergey Dmitriev noted that IUPAC is expected to recognize the elements 116 and 114 by the end of this year.

Georgy Flerov — Soviet nuclear physicist, an expert in the field of nuclear fission, the synthesis of new chemical elements, new types of radioactivity. Member of Soviet nuclear weapons. In 1940, together with Konstantin Petrzhak discovered a new type of radioactive transformations — the spontaneous fission of uranium. Thanks to the ideas Flerov at JINR obtained a whole series of chemical elements. The scientists named the Laboratory of Nuclear Reactions, JINR.

On Earth, the chemical elements heavier than uranium, which has the serial number 92 in the periodic table are not found because they are radioactive, and their nuclei are split up over four billion years of Earth’s history. All elements heavier than uranium are synthesized in special nuclear reactors and accelerators in the collision of nuclei of other elements. From the middle of the last century, nuclear physicists around the world are looking for the so-called "island of stability" of superheavy elements.

The nuclei of superheavy elements are very unstable and break up into smaller nuclei and particles in a matter of seconds. However, in the 50’s and 60’s of last century, physicists have developed a theory that the nuclei of some of superheavy elements may have a special configuration that allows them to be minutes, hours, days and months. Some scientists believe that superheavy elements can be stable even in the course of millions of years.
