On starting year 2016, chemistry lover got good news that 7th row of periodic table is completed by finding 4 new elements. Actually their existence was found earlier but now official position of this elements is
declared. Atomic no. (i.e. numbers of protons per atom) of this new entries are 113, 115, 117 and 118 have the monikers Uut, Uup, Uus, and Uuo respectively. If you stuck periodic table on wall than now you have to change it :D. This new elements have highest atomic weight.
New elements got names from researcher’s name.Elements with more than 92 atomic number are not stable and not found in nature normally, but scientist’s work of decades make sucesssful tosynthesize them and prove their brief existence.
Identification of element 113 is goes to scientists at the RIKEN Institute in Wako, Japan, while for 118. Elements 115 and 117 credit goes to Russian-U.S. collaboration from the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California.
This four element was not found naturally but produced in laboratory. For producing elements Light nuclei are hit together and delay is tracked from super heavy element. This element is exist only for fraction of second so discovery of them was very difficuilt.
“The chemistry community is eager to see its most cherished table finally being completed down to the seventh row,” Professor Jan Reedijk, President of the Inorganic Chemistry Division of IUPAC, said in a statement.
The experiments offered more than a checklist of new elements. By studying how the massive nuclei of the new elements decay, researchers gained insight into the forces that hold atoms together. According to their findings, elements heavier than any yet created might have conformations that are especially stable—suggesting that if we can ever make atoms that big, they might stick around for longer than a few microseconds.
Stay Connected and Happy Reading J
