Thorium, 90, Arrupe Jesuit High School, Colorado USAThorium: In my illustration of thorium I drew several things. These include the name and symbol of the element in graffiti-art style. The color of the graffiti piece is important as well because it refers to the color of thorium which is a grayish color. I also drew a glow in the background to represent thorium as it is heated up. I also tried to capture thorium’s radioactivity in the tile along with its toxicity.
