Add 'super heavy' element in Mendeleev periodic table

The Mendeleev periodic table will be supplemented with the 112th 'superheavy' element. This is the result of the experimental work after more than a decade of German scientists.

The Mendeleev periodic table will be supplemented with the 112th 'superheavy' element. This is the result of the experimental work after more than a decade of German scientists.

However, this element has no name. According to Professor Sigurd Hofmann, head of the Research Center for Heavy Ion Research, it is necessary to propose a name for the element they discovered, before it was officially added to the periodic table.

The fusion experiments that Hofmann and his colleagues conducted at the center showed the existence of elements with atomic numbers from 107-111. These elements are called 'superheavy', their numbers represent the number of protons and neutrons they carry.

The Mendeleev periodic table will be adding many new elements.

To create the 112 element, Hofmann's team used an accelerator with a 120-meter tunnel to burn charged zinc atomic rays. The nuclei of the two elements combine to form the nucleus of a new, heavy but unstable element. They begin to split or decay right after forming within a few milliseconds. Based on the measured energy in the experiment, the scientists calculated the size of the decaying nucleus.

Such experiments give a small success rate, because the existence of a new element is extremely short. Therefore, scientists power the accelerator to conduct experiments longer and find other unstable and hard-to-find elements. This is why it took a long time to find element 112, officially recognized by the Pure Chemistry and Applications Association (IUPAC).

IUPAC temporarily named the element ununbium, with the prefix 'ununbi' being the derivative of the Latin 'one one two' count in Latin, but Professor Hofmann's group found it necessary to propose an official name for this element.

Professor Hofmann also revealed the higher goal: 'We are conducting similar experiments to find element 120. This element has not yet appeared but we believe it exists and with the time of burning The beam is long enough, it will appear '.
