Silicon – expert written, user friendly element information

Oxygen (47.3%) and silicon (27.7%) together make up 75% of the weight of Earth's crust. Most of the crust's silicon exists as silicon dioxide; we are familiar with this as sand or quartz. Silicon is the eighth most abundant element in the Universe; it is made in stars with a mass of eight or more Earth suns.

Reade Advanced Materials - Silicon Dioxide, High Purity .

The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

The Quartz Page: Physical Properties

The central silicon atom is surrounded by 4 oxygen atoms (one of them is omitted for readability). The overall formula of quartz is SiO 2, and since every oxygen atom carries the same extra amount of negative charge taken from a silicon atom, the central silicon atoms carries 2 positive charges and the oxygen just one negative charge.
