Silicon is an essential component of modern electronics because it is an element with very special properties. Namely, silicon in the pure form is a semiconductor, which means it possess properties of both a metal (which conducts electricity) and an insulator (which blocks electricity).
Silicon is used for electronic devices because it is an element with very special properties. One of it's most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others. ... Silicon is also an abundant element on Earth
