Black phosphorus make bonds

WebTwo electrons are shared between each hydrogen atom and the carbon atom bonded to it, and four electrons are shared between the carbon atoms. Walls made of paraffin wax, a covalent compound, help keep the temperature in a room steady as night changes into day and day into night. Black phosphorus has an orthorhombic pleated honeycomb structure and is the least reactive allotrope, a result of its lattice of interlinked six-membered rings where each atom is bonded to three other atoms. In this structure, each phosphorus atom has five outer shell electrons. See more Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids. Solid violet and black allotropes are also known. Gaseous phosphorus exists as diphosphorus and atomic phosphorus. See more Monoclinic phosphorus, or violet phosphorus, is also known as Hittorf's metallic phosphorus. In 1865, Johann Wilhelm Hittorf heated red phosphorus in a sealed tube at 530 °C. The upper part of the tube was kept at 444 °C. Brilliant opaque See more Ring-shaped phosphorus was theoretically predicted in 2007.
