WebFormation of tetrahedra requires bond angles of 60° instead of the preferred 90°–109° angles, so that white phosphorus is a relatively unstable, or metastable, form. It changes spontaneously, but slowly, at temperatures around 200 °C (390 °F) or higher, to a polymeric form called “ red phosphorus.” WebRed Phosphorus and Violet Phosphorus (Polymeric) Red Phosphorus has more atoms linked together in a network than white phosphorus does, which makes it much more stable. It is not quite as flammable, but given enough energy it still reacts with air. For this reason, we now use red phosphorus in matches. Figure 4: red phosphorus is in safety matches.
