- Silicon is found in measurable amounts in practically every rock, in all natural waters, in sand, in glass, in the atmosphere (as siliceous dust), in many plants and in the skeletons, tissues, and in the body fluids of some animals.
- It holds on to other atoms so tightly that it is not easy to isolate.
- It is never found in a free state, but always in combination either with oxygen as silica, or with oxygen and aluminum, magnesium, calcium, sodium, potassium, iron, and other elements in the numerous silicate materials which comprise rocks, soils, and clays.
