The Elements: Silicon

The Earth's crust is largely composed of silicate minerals, which include silicon combined with oxygen and other elements. Silicon is prevalent in nature, found in forms such as sand and quartz, and even in celestial bodies like the sun and stars. It is a highly versatile element, used in making concrete, bricks, glass, and plastics. Silicon's most significant contribution is in the form of silicon chips, which have revolutionized computing by enabling the development of smaller and more powerful computers.
