Consider the table in the chapter listing the various silicate structures of common rock-forming minerals. Determine the silicon to oxygen ratio for each type and express it as a decimal fraction. This can be done by dividing the number of silicon atoms by the number of oxygen atoms. In the first category (isolated tetrahedral), for example, the ratio is 1:4 or 0.25. What can you conclude from this?
