No gold is not a silicate, because it does no contain oxygen and silicon.
A mineral that lacks silicon or oxygen is called native elements. These minerals consist of a single element or a combination of elements without silicon or oxygen in their chemical composition. Examples include gold, silver, copper, and sulfur.

There are 4 oxygen ions and 1 silicon ion in a silicon- oxygen tetrahedron.
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.
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.
"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.
A silicon-oxygen bond is considered polar due to the difference in electronegativity between silicon and oxygen. Oxygen is more electronegative than silicon, causing a partial negative charge on oxygen and a partial positive charge on silicon.
One is silicon, but I don't know the other:(oxygen
One example is oxygen. Oxygen combines with silicon to form silicon dioxide, SiO2.
The symbol for silicon is Si, and the symbol for oxygen is O.
