Silicon
Silicon is the basis of the widely used synthetic polymers called silicones. The late 20th century to early 21st century has been described as the Silicon Age (also known as the Digital Age or Information Age) because of the large impact that elemental silicon has on the modern world economy.

Silicon (pronunciation SIL-ee-ken [2]), represented by the chemical symbol or formula Si [1], is a semiconductor [20] belonging to the carbon family [23]. It can be of two types, amorphous powder and solid crystalline form.
Learn about the history, properties and applications of silicon, a metalloid with semiconducting properties and the second most abundant element on Earth. Find out how silicon is formed, isolated and purified, and what are its allotropes and isotopes.
In its pure form, silicon is a semiconductor, making it invaluable in the electronics industry for the fabrication of integrated circuits and microchips. Additionally, silicon is used in solar panels, glass production, and as a component in silicon-based polymers like silicones.
Silicon makes up 25.7% of the earth's crust by weight, and is the second most abundant element, exceeded only by oxygen. It is found largely as silicon oxides such as sand (silica), quartz, rock crystal, amethyst, agate, flint, jasper and opal.
