A basic silicon-oxygen tetrahedron consists of one silicon atom at the center bonded to four oxygen atoms at the corners. Therefore, there is one silicon atom in a basic silicon-oxygen tetrahedron.
Four.
"silicon-oxygen" is essentially meaningless. Silica contains silicon and oxygen in the proportion 1:2, so is sometimes called "silicon dioxide", but it doesn't exist in the form of individual SiO2 molecules; they're bonded to each other in a large network.
Quartz is rich in the element silicon. It is composed of silicon dioxide (SiO2).
The compound silicon monoxide (SiO) has only two atoms; one silicon atom, one oxygen. The prefix "mono" tells you there is only one oxygen attached; "bi" or "di" (such as in silicon dioxide) would tell you there are two oxygens (for total of three, in that example).
SiO2 is a macromolecule. Each silicon atom is covalently bonded to four oxygen atoms and each oxygen atom is covalently bonded to two silicon atoms.
Silicon dioxide is a molecule made of one silicon and two oxygen for a total of three atoms.
a Tetrahendron consists of 4 sides
Silicon dioxide is composed of silicon and oxygen atoms in a 1:2 ratio. It is a common mineral found in many forms, including quartz and sand.

The molecular formula for silicon dioxide is SiO2, so there are a total of three atoms; one silicon atom, and two oxygen atoms.
The chemical formula of Silicon dioxide is SiO2. Two oxygen atoms are bond to a silicon atom. This compound has 3 atoms per molecule.
