phosphorus (P) - David Darling
Phosphorus (P) is a highly-reactive, poisonous, nonmetallic element (see nonmetal) that occurs naturally in phosphates, notably apatite (Ca 3 (PO 4) 2).It was discovered by Hennig Brand in Hamburg in 1669 (Fig 1). The name comes from the Greek phosphorus, meaning "bringer of light," because it glows in the dark.It is the eleventh most common element in the Earth's crust.

Which is more reactive sulfur or phosphorus ...
This applies for white phosphorus; red phosphorus is basically a polymer of white phosphorus and the bonds are under less strain making it less reactive. Sulfur, however, normally exists as a ring of sulfur atoms of 8, although rings of 7 etc. exist. There is much less bond strain in this and it is considerably stable.
