As of Dec. 30, 2015, scientists have officially completed the seventh row of the Periodic Table of Elements. While scientists may have predicted their presence in the past, the last four elements have officially been proven to exist. This alteration has been made possible by the collaboration of scientists in America, Japan and Russia.

“The chemistry community is eager to see its most cherished table finally being completed down to the seventh row,” said President of the Inorganic Chemistry Division of IUPAC Professor Jan Reedijk.

These four elements are named Uut (Ununtrium), Uup (Ununpentium), Uus (Ununseptium) and Uuo (Ununoctium). The new, non-natural elements were discovered while smashing together light nuclei and tracking the decay of the proceeding elements. Various scientists around the world have contributed to the discovery of these elements. The credit for element 113 has been given to scientists at the RIKEN Institute in Wako, Japan. A Russian-U.S. collaboration from the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California takes the recognition for element 118 as well as elements 115 and 117.

“Personally, I was never intrigued by the periodic table, but I do appreciate the fact that it is now complete,” said senior Connor Parille. “It just goes to show you how much science has advanced.”

Although the table is theoretically complete, scientists plan to take measures to discover more elements. Whether they are natural or man-made, the periodic table is set to expand sometime in the future.
