History Silicon Simcoa

Silicon (chemical formula Si) is a stable, relatively light, lustrous, grey element. It doesn't occur in nature in its elemental form but combines with oxygen and other elements to form oxides or silicates. Silicon, occurring in these forms, is the second most abundant element on Earth (oxygen being the most abundant). The combination of silicon with oxygen (SIO2) forms the mineral silica.
