The Updated Periodic Table

Earth’s Elements

More Elements: The Periodic Table of Elements is now bigger with the addition of four elements to the table’s seventh row (or period as it is formally known), thus completing it, reports the International Union of Pure and Applied Chemistry (IUPAC), in Zurich, Switzerland. The nations responsible for the discoveries—Japan, Russia and the USA—have been invited to suggest permanent names and symbols. These elements have atomic numbers 113, 115, 117 and 118. Nathaniel Scharping writes for Discover Magazine: “The elements’ existence has been documented by researchers from Russia and the United States, as well as a separate team from Japan, for several years, but they awaited official review by the IUPAC to be formally accepted. Now that the confirmation process is complete, the researchers will submit permanent names for their elements. The IUPAC states that elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist. The elements are currently known by placeholder names, such as the ever catchy ununseptium for element 117. The four newest discoveries will join other “superheavy” elements in the seventh period of the periodic table, including flerovium and livermorium, which were added in 2011.”
