Silicon is the 14th element in the periodic table, sharing properties with its lighter analogue carbon. Like carbon, it bonds easily with many other elements to form a wide range of materials such as glass (silicon dioxide), computer chips (silicon doped with cesium or tellurium) and wood (silicon tetrachlorine oxide). Silicon is extremely abundant in the earth's crust, and silicon dust particles play an essential role in cloud formation.
