Silicon Dioxide Silica Structure Revealed

The video explains the structure of silica, focusing on SiO4 units where each silicon atom is tetrahedrally bonded to four oxygen atoms. The structure forms a three-dimensional network through covalent bonds, creating cyclic rings of alternating silicon and oxygen atoms. The molecular formula of silica is SiO2, not SiO4, because each oxygen atom is shared between two silicon atoms, resulting in a 1:2 silicon to oxygen ratio.
