Zirconium, 40, Washtenaw Christian Academy, Michigan USA

Zirconium: My tile incorporates four elements of Zirconium: the element's symbol, atomic number, color (a lustrous, grey-white, and transitional metal), and electron diagram. The gems represent the color of the element and its lustre. The 40 represents the atomic number and the number of proton in Zirconium. The "Zr" on the tile is the symbol of the element and is on the periodic table. The final item on this tile is the electron diagram. Zirconium has 40 electrons and 40 protons, so this picture has 40 electrons separated into the different levels. Zirconium was discovered by the German chemist, Klaproth.
