Silicon is a metalloid element with the chemical symbol Si and atomic number 14. It is the second most abundant element in the Earth’s crust, after oxygen, and is found mainly in the form of silicon dioxide (SiO₂) and silicate minerals. Silicon is known for its unique properties—it is hard, brittle, and shiny, and acts as a semiconductor, which means it can conduct electricity under certain conditions. Because of this, it plays a vital role in the electronics and computer industries, forming the backbone of microchips, transistors, and solar cells. Silicon is also widely used in the production of glass, ceramics, and concrete. Pure crystalline silicon is obtained through chemical purification and is essential for modern technologies. Its combination of abundance and utility makes it one of the most important elements in today’s world.
