Silicon dioxide is an inorganic compound with the chemical formula SiO2. Silicon atoms and oxygen atoms are arranged in a long-range order to form crystalline silicon dioxide, and short-range order or long-range disordered arrangement to form amorphous silicon dioxide.
In a silicon dioxide crystal, the silicon atom is located in the center of the regular tetrahedron, and the four oxygen atoms are located on the four top angles of the regular tetrahedron, and many such tetrahedrons are connected by the oxygen atoms of the top angles, each oxygen atom is shared by the two tetrahedrons, that is, each oxygen atom is combined with two silicon atoms.
The simplest form of silicon dioxide is SiO2, but it does not represent a simple molecule (only the ratio of the number of atoms of silicon and oxygen in the silicon dioxide crystal).
Pure natural silica crystal, is a hard, brittle, insoluble colorless transparent solid, often used in the manufacture of optical instruments.
