Two New Elements Join Periodic Table

"Over the past 250 years, there have been basically 100 new elements discovered," said Paul Karol, a chemistry professor at Carnegie Mellon University and chair of the committee that recommended the additions. "But it is bec more and more difficult to do this so when a new element is discovered, it's actually pretty exciting."
The pair were found through atom-smasher experiments called cross-bombardments, according to research published by the International Union of Pure and Applied Chemistry.

The experiments, hosted at the Joint Institute of Nuclear Research in Dubna, Russia and in cooperation with a U.S. team based at Lawrence Livermore National Laboratory in Berkeley, California, smashed calcium together with plutonium to make 114, and calcium with curium for 116.
