Web1. Glass has an amorphous, disorganized network structure. 2. The primary unit of glass structure is the SiO4 tetrahedron, in which each Si atom is surrounded by four oxygen atoms in a tetrahedral configuration. 3. Most oxygen atoms are shared between neighboring tetrahedra, so that the overall chemical formula of fused silica is SiO2. 4. Webanswer choices. Ionic solids are held together by stronger binding forces. Ionic crystals are soft and easy to break. Covalent solids are held together by stronger binding forces. Covalent crystals contain a greater number of bonds. Question 46. 30 seconds. Q.
