Arey!! Who said two whole SiO2s have to surround anything? Read it again man! And yes, we have to know this.

Naaaaaah.. MS mein it was written. That two Si will surround each O2.
You what? Chem is so bugging... all this formula, valency, ions and all

Are you talking about the structure of sand? Yes, each silicon atom is surrounded by two oxygen atoms.

And each silicon is surrounded by how many O2 then?

O2 is a molecule. Silicon dioxide has a giant covalent structure. Each silicon atom is covalently bonded with two oxygen atoms.

I can't visualise it's structure, actually...

You got the Federal Chemistry, check out the bonding topic. There is structure for sand and diamond both.
