Lutetium, 71, Charlottetown Rural High School, Charlottetown PEILutetium: Our tile represents lutetium, element 71, the last of the lanthanide series. The main inspiration for this tile came from a viewing of the University of Nottingham site, The Periodic Table of Videos, by Martyn Poliakoff et al. Students learned that lutetium is used to date meteorites and had been named after Lutetia, the Roman town that gave rise to present day Paris. Created by Renée Dahn, the tile depicts the Eiffel Tower, the emblem of Paris, against a night sky of stars with one lone meteorite.
