In Silica, Yes, 4:1 (Tetrahedral structural unit of silica )
[SiO2 ]
Four.
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).
"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.
Oxygen and Silicon are elements in their own right. They do NOT contain aanything else. However, Silicon and Oxygen can combine to form the molecule 'Silicon Dioxide' ( SiO2 ), of which is sand on the beach is an impure form, mixed with oxides of other elements.
In a molecule of silicon dioxide, there are covalent bonds between silicon and oxygen atoms. Silicon shares electrons with oxygen to form a stable structure, creating a network of alternating silicon and oxygen atoms.
This is the SiO4 anionic group. Thus, the answer you need would be that there are more oxygen atoms.

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.
In a molecule of silicon dioxide, there are covalent bonds between silicon and oxygen atoms. Silicon shares electrons with oxygen to form a stable structure, creating a network of alternating silicon and oxygen atoms.
The chemical formula of silicon dioxide is SiO2. The atomic ratio oxygen/silicon is 2.
Silicon (a metalloid) and oxygen (a nonmetal) are the two elements that compose silicon dioxide (SiO2).

Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
