Hey, its been a few months since I've recapped this stuff
No worries
Anyway. I'm just really confused whether this thread is about Silicon Dioxide or Sulfur Dioxide now. Because OP wrote S as the symbol but said Silicon
OP for the record:
Silicon dioxide is giant covalent with each silicon singly bonded to 4 oxygens. Sulfur dioxide is simple covalent with each sulfur doubly bonded to 2 oxygens, and is bent.
