Phosphate glasses can be made with a range of structures, from a cross-linked network of Q 3 tetrahedra (vitreous P 2 O 5) to polymer-like metaphosphate chains of Q 2 tetrahedra to ‘invert’ glasses based on small pyro- (Q 1) and orthophosphate (Q 0) anions, depending on the [O]/[P] ratio as set by glass composition. “SO3 Molecular Geometry, Lewis Structure, and Polarity Explained.” Geometry of Molecules, 21 July 2017, Available here. It is singly bonded to two oxygen atoms and doubly bonded to one oxygen atom. Since there are no lone pairs around the Phosphorus, and it has 4 densities around it, the share is tetrahedral. –CH 3 –COO – Hybridisation of C sp3 sp2 Molecular geometry about C tetrahedral trigonal planar Approximate bond angles about C 109o 120o The actual structure of the acetate ion is a weighted combination of all resonance structures. . Draw an acceptable Lewis structure for PCl 5 , a compound used in manufacturing a form of cellulose. Step 1: Find valence e- for all atoms. Include all formal charges and lone-pair electrons.
