Most of the body's supply of this element comes in a mineral of calcium and this element called apatite.
This element forms two new bonds in the Arbuzov reaction, and it is bonded to fluorine in the nerve agent Sarin. A triphenyl derivative of it is used alond with DEAD in the Mitsunobu reaction, and a reagent often used to convert carboxylic acids to acyl bromides is this element's pentabromide. Most of the body's supply of this element comes in a mineral of calcium and this element called apatite. Allotropes of this element include the chain-like red and the tetrahedral white, and the Wittig reaction requires a ylide containing this element. Adjacent DNA bases are linked by diester bonds containing this element. For 10 points, name this element in nitrogen's group with symbol P.
