Uranium

Port Credit Secondary School, Mississauga, Ontario, Canada

Uranium: Uranium was discovered by Martin Klaproth, a German scientist who stumbled upon it while examining pitchblende. Because uranium is radioactive, the big picture is the three wedges of the symbol for radioactivity. Uranium is known for its uses in nuclear power, so to show this the left wedge is a nuclear power plant. The top wedge of the radioactive symbol is Martin Klaproth and the right wedge is pitchblende. I also gave the atomic number on the bottom-right corner of the tile a fiery texture symbolizing the element’s reactivity. Uranium is silver and very lustrous; thus I made the element symbol for Uranium silver and glowing as if it is shining.
