does anyone know the exact structure of glass?  i know it is silicon dioxide...but i've heard it arranged tetrahedrally so that there are a bunch of Si-O-Si-O-Si bonds happening with O-Si-O-Si-O going up vertically from each of the Si atoms in the above horizontal pattern.  eventually these patterns end.  if the Si were to doubly bond the oxygen at the end, the Si would be making 5 bonds... and i know they dont ALL end in Si-O-H because fluorine doesn't attack glass THAT quickly

so...what does it look like exactly?

Glass is an amorphous material so it doesn't have exact crystal structure. It's just bunch of O-Si-O chains/grids/rings tied together with some -OH groups and additives mixed inbetween. Tetrahedrically arranged SiO2 is crystalline quartz.
