Why is the formula SiO2 not SiO4?

Silicon’s 3p and oxygen’s 2p orbital has size mismatch for the formation of pi bond, hence Si doesn’t form pi bonds with oxygen. Silicon in SiO4 is SP3 hybridized and got tetrahedron geometry. Silica takes the formula SiO2 instead of SiO4.

Is silicon atomic or molecular?

Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it.

Does silicon have a molecular structure?

Pure silicon is a hard, dark gray solid with a metallic lustre and with a octahedral crystalline structure the same as that of the diamond form of carbon, to which silicon shows many chemical and physical similarities.
