Bonding of Silicon Dioxide

Looked through the specification and this is something we need to know for AQA GCSE

Can someone tell me how silicon dioxide is bonded thorough a dot and cross diagram?

Thanks!

The formula is: SiO2 and I think the dot and cross diagram for it would be:

Sorry for my rubbish drawing (crosses are from silicon and dots are from oxygen)

Nooooooooooooooo!

It's a giant structure with each silicon atom bonded tetrahedrally to four oxygen atoms and each oxygen atom bonded to two silicon atoms ...
