Electron Arrangement and Colors of Light

Students in Mr. Bunger’s Chemistry class have started learning about the way electrons are arranged in atoms. One of the ways that scientists began to learn about electron structure was by observing the way certain colors of light are emitted from different metals as they burn. In the lab students heated compounds containing different metals using a Bunsen burner and then observed the color of light emitted. Different metals emit different colors of light because their electrons have a different arrangement. This lab is designed to provide a visual reinforcement of this fundamental chemical concept, and give students a memorable experience to fit these concepts into real life.
