How many valence electrons does Silicon have?

4 as its in group four:
SiO2 ====> O=Si=O
CH3
|
Si(CH3)4 ====> H3C - Si - CH3
|
CH3
incidentally the second one is tetramethylsilane and is used to give the reference (0ppm) peak in [proton] NMR
Note the CH3 bonds should be with the drawn out structure...

Four, because it's in Group 4 (or 14 if you are in the US!).
