Phosphorus is a chemical element with symbol P and atomic number 15. As an element, phosphorus exists in two major formsâ white phosphorus and red phosphorus âbut due to its high reactivity, phosphorus is never found as a free element on Earth.Instead phosphorus-containing minerals are almost always present in their maximally oxidised state, as inorganic phosphate rocks. White phosphorus, called WP (slang term Willie Peter) is used in military applications as incendiary bombs, for smoke-screening as smoke pots and smoke bombs, and in tracer ammunition. 2  It is also a part of an obsolete M34 White Phosphorus US hand grenade.
