http://hyperphysics.phy-astr.gsu.edu/hbase/Solids/lattice.html WebDec 6, 2013 · Every 14 Si atom is surrounded by 4 8 O atoms. On the other hand, every 8 O atom is surrounded by 2 14 Si atoms. Suppose that the number of Si-O bonds is n, then the number of 14 Si atoms is n / 4, while the number of 8 O atoms is n / 2. Therefore you arrive at the formula Si O 2.
