Silicon Dioxide Covalent Crystal Structure Model Kit – 68 Atoms

Silicon dioxide (SiO2) covalent crystal structure model kit for demonstrating the three-dimensional giant covalent network found in silicon dioxide and crystalline quartz.

Each silicon atom bonds to four oxygen atoms, while each oxygen atom bonds to two silicon atoms, producing a continuous three-dimensional network. The model helps students visualise the tetrahedral arrangement around silicon centres and the bonding responsible for the structure of silicon dioxide.
