The ion at the center of a silicate tetrahedron is surrounded by?
There are 4 oxygen ions and 1 silicon ion in a silicon- oxygen tetrahedron.
Yes. Refer to the related link for an illustration.
One "small" Si ion surrounded by four "large" oxygen ions, forming a tetrahedron.

The preponderance of the elements in sand are silicon or oxygen, with twice as many oxygen atoms as silicon atoms. In naturally occurring sand, some impurities with additional elements as iron are usually present in small amounts.
The chemical formula of Silicon dioxide is SiO2. Two oxygen atoms are bond to a silicon atom. This compound has 3 atoms per molecule.

Silicate tetrahedra. The tetrahedra are spanned by oxigen atoms, and right in the middle, there is a silicon atom. The chemical formula for one silicate tetrahedron is SiO4 The actual rate between silicon and oxigen can change as the tetrahedra are linked together, as different tetrahedra can share an oxigen atom with eachother.

How many silicon atoms are in a basic silicon-oxygen tetrahedron?i am thinking about 4..

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.
4
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 the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon--oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO2.There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings
Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
