Unlike graphene, a single-layer orthorhombic allotrope of this element has a band gap. Exposure to this element can lead to BON, its associated necrosis of the jaw. It is used as a radioactive marker in Northern and Southern blots, and its pentachloride violates the octet rule. A violet-colored allotrope of this element is named for Hittorf. The oxidation of this element's white allotrope gives rise to chemiluminescence while this element's red allotrope is often used in the tips of matches. For 10 points, name this element which forms the backbone of DNA and has the chemical symbol P.
