Silicon (Si) is a chemical element and atomic number (Z) 14, group 14, period 3, and atomic weight 28.085. The Silicon (Si) is the most abundant electropositive element in The Earth’s crust that is purely electropositive in its chemical behaviour. Silicon is an intrinsic semiconductor in it’s purest form, although the intensity of its semi-conduction is highly increased by introducing small quantities of impurities. Silicon is the principal component of glass, cement, ceramics, most semiconductor devices, and silicones, also an important constituent of some steels and a major ingredient in bricks.
