The long chain compounds formed by silicon are very reactive.
Non-metallic chemical element silicon (Si) is a member of the carbon family.
The octahedral crystalline structure of pure silicon is a hard, dark grey solid with a metallic lustre.
Since pure silicon is too reactive to be found in nature, it is instead mixed with other elements or oxygen to form silica, which is present in almost all rocks, sand, clays, and soils. the long chain compounds formed by silicon are very reactive.
