glass structure

[budullewraagh]

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 at the ends?
