Hassium: This tile was designed by Erica Binion, a junior at East Syracuse Minoa High School, East Syracuse, New York and the East Syracuse-Minoa (ESM) American Chemical Society (ACS) Chem Club. The history of this element is the theme for our tile. German scientists at the Darmstadt Institute for Heavy Ion Research discovered Hassium in 1984. Hassium was first synthesized using Universal Linear Accelerator (UNILAC), a heavy ion particle accelerator, which can be seen in the background of the image along with charged particles necessary for this synthesis with Fe-58 and Pb-208 smashing together to form Hs-265. At the bottom of the tile there is a quote from the German scientist, Gottfried Münzenberg, who helped discover this element in 1984. This quote is written in German but translates to “that we see our beautiful land of Hesse honoured.”
