Following earlier reports that the claims for discovery of these elements have been fulfilled [1, 2], the discoverers have been invited to propose names and the following are now disclosed for public review:
The claims for four new elements have been validated in two new reports from the IUPAC/IUPAP Joint Working Party (JWP) and accepted for publication in Pure and Applied Chemistry. The addition of the four, namely elements 113, 115,117, and 118, represents a significant milestone because it completes the seventh row of the Periodic Table. The new elements add to the remarkable progress in extending the periodic table following 114 and 116 validated in 2011, and element 112 validated in 2009.
The periodic table of chemical elements may welcome a new element to its big family soon. An international team, led by researchers from Lund University, has presented evidence that confirms the existence of a new element with atomic number 115. The provisional name of the element is ununpentium. The experiment was conducted at the GSI Helmholtz Center for Heavy Ion Research, located in Darmstadt, Germany.
In the periodic table, chemical elements are arranged by their atomic numbers, i.e. the number of protons in the atom’s…
