PERIODIC TABLE OF ELEMENTS OF A NEW TWO
Table of chemical elements now have two new members and flerovium livermorium. The second new element was introduced by the international union of pure and applied chemistry, earlier this month.The new name will be socialized before the official perodik inserted into the table.
Meanwhile, three other elements are also in the process of completion and will be the element number 110.111 and 112. The five elements are very large and unstable is only made in the laboratoryonce experienced rapid separation into a new element.Little is known of this new element because it is not found in nature. The unstable nature makes the researchers could not do anything to berekspeimen with this unsuer.These elements are very heavy and similar uranium so-called transuranium elements.
Livermorium and flerovium will be one hundred elements to 116 and 114, and has been officially accepted in the table since last June, in fact this element has been found more than ten years ago, but had to undergovarious experiments to recognize it. 113,115,117 and 118 elements have also been produced at the joint Institute for Nuclear Research, Dubna, Russia.
But all four of them have not been confirmed by the international union. so confirmed these elements are also introduced to the public soon.
CONTRIBUTION OF SCIENTISTS
Same with the four candidates of the other elements, livermorium and flerovium also produced in the same laboratory.There, Russian researchers working with American researchers from Lawence Livermore National Laboratory, California.
The element 114 previously known as ununquadium. Flevorium named [F1] to commemorate the founder of the Flerov Laboratory of Nuclear Reactions physicist who is also Russia, Georgiy Flerov [sebilanbelas thirteen-nineteen ninety].Flerov work Dulu.hasil Joseph Stalin during the early development of Soviet atomic bomb project. The researchers first looked flevorium after the firing of calcium ions into a plutonium.
While the first element named ununhexium, almost moscovium named according to the name of the province where the lab was located [moscow]. But finally, some American researchers gave the name livervorium [LV], in accordance with the original name of their laboratory, Livermore.
Livermorium was first observed in 2000 when the scientists crush for calcium atoms and curium.
"Proposing the names of these elements is not only the contribution of scientists from laboratories in the field of nuclear, heavy and super heavy elements, but also the phenomenal cooperation between scientists in the two locations," said Bill Goldstein, director of Lawrence Livermore NationalLab'Physical and Life Science leader, on 3 December last.
