Learn about our Editorial Process Updated on February 08, 2018 Phosphorus is one of the elements that had its own alchemy symbol. Alchemists felt that light represented the spirit. The non-metallic element phosphorus was of interest because of its apparent ability to contain light, as evidenced by the characteristic glow-in-the-dark phosphorescence of phosphorus compounds. Pure phosphorus also has the ability to spontaneously burn in air, but the element was not isolated until 1669. Phosphorus was also an ancient name for the planet Venus, when seen before sunrise.
