Image description

With the aid of the spectroscope, which they invented in 1859, German chemist Robert Bunsen and physicist Gustav Kirchhoff discover that vaporizing a substance creates a unique "signature" spectrum, which can be used to identify it. Using the spectroscope, in 1860, Bunsen and Kirchhoff discover two new alkali metals—cesium and rubidium.
