P - Phosphorus - periodic table of the elements

The flammable non-metal was discovered in Germany in 1669 by Hennig Brand who precipitated it from urine (don't ask me how, or where he got the urine). Phosphate buffers are used in general chemistry, and phosphoric acid is used for synthesis in organic chemistry.
