The chemistry of phosphorus pt.1 By Laura Roa

Chemical properties Different from Nitrogen: Nitrogen’s pi bonds Nitrogen’s electronegativity Size of Phosphorus atom D orbitals on Phosphorus

Elemental form differences Several solid forms of phosphorus. White phosphorus Black phosphorus Red phosphorus Forms phosphides

Phosphine Na3P + 3 H2O = PH3 + 3 NaOH (formation) Analogous to Ammonia Small affinity for protons Pyramidal molecular structure: Exception to VSEPR

Phosphorus oxides and oxyacids Phosphorus reacts with oxygen to form oxides: Tetraphosphorus decoxide Affinity Dehydrating Dissolvation Phosphate minerals
