Cesium, 55, Andover High School, Michigan USA

Cesium: For my tile I used many components of the element cesium. The thermometer surrounded by flames symbolizes a low melting point and the tube of a light gold metal represents cesium in its liquid form. Cesium is also used in atomic clocks so I decided to draw an atom in an old fashioned clock. The Erlenmeyer flask with flames coming out of it represents that Cesium is extremely reactive when it comes in contact with water.
