The management of the International Union of Pure and Applied Chemistry (IUPAC) has endorsed the breakthrough of elements 113, 115, 117 and 118. They declared that they have sufficient justifications to give an indefinite place to these elements in the periodic table. These elements are synthesized by scientists in the laboratory, we won’t find them in nature. The elements 113, 115, 117 and 118 had non-permanent names and locations in the periodic table. Up-till now these elements are placed in the seventh row of periodic table.

The IUPAC has reported that a team of researchers from Russia and USA has checked the standards to prove the existence of the other three elements 115, 117 and 118. This team of researchers will be requested to come and suggest the names of these elements.
The president of the Inorganic Chemistry Division of IUPAC, Jan Reedijk said last week that the chemists are very excited to see the most up-to-date table finally being completed down to the seventh row.
The administration suggests that these elements should be named after some myth, a mineral, a scientist or a property. Before the final decision about the names and symbols, these will be presented to public for their opinion.
The details about the discovery of element 113 have posted in the Journal of Physical Society of Japan. But the detailed report on the discovery of elements 115, 117 and 118 is not published yet.
The researchers of RIKEN delineated that how they produced an atom of element 113 in 2003 by bombarding a thin layer of bismuth with zinc ions travelling at about one-tenth the speed of light.
The team noticed the dubnium-262 (element 105) which was considered to be the decay matter of element 113. But they couldn’t prove it due to the lack of evidences. The team performed another experiment in which a sodium beam was collided with a curium target, creating borhium-266 and its daughter nucleus, dubnium-262.
This experiment was proved to be more effective as it laid a stronger foundation for this discovery. It took almost four years for the IUPAC to confirm that their discovery meet with the ideal standards set for the discovery of elements.
RIKEN researcher, Kosuke Morita said that now we are aiming to explore the chemical properties of the elements 119 and beyond, present in the seventh and eighth row of the periodic table. And someday we may discover the Island of Stability.
