  • Phosphorus Wikipedia

    Phosphorus is a chemical element with the symbol P and atomic number 15 Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on EarthIt has a concentration in the Earth's crust of about one gram per kilogram (compare copper at about 006 grams)
