Changing the Periodic Table? “For the first time in history, a change will be made to the atomic  weights  of  some  elements  listed  on  the  Periodic  table  of  the  chemical elements posted on walls of chemistry classrooms and on  the inside covers of chemistry textbooks worldwide.” 1 “…  As technology improved, we have discovered that the numbers  on our chart are not as static as we have previously believed," says  Dr.  Michael  Wieser,  an  associate  professor  at  the  University  of  Calgary, who serves as secretary of the International Union of  Pure  and  Applied  Chemistry 's  (IUPAC)  Commission  on  Isotopic  Abundances and Atomic Weights. 1 ScienceDaily . Retrieved September 14, 2011, from  http://www.sciencedaily.com/releases/2010/12/ 101215133325.htm    (original source: Pure Appl. Chem., 2011, Vol. 83, No. 2, pp. 359-396)
