What is the difference between "silicon" and "silicone"?
Silicon is a hard, non-metallic chemical element (symbol Si) that is the basis of computer chips and most rock and sand, while silicone is a man-made, rubbery material built from silicon and oxygen, used in sealants, kitchenware, and medical products. Chips are silicon; flexible bakeware is silicone.
Why is it called "Silicon Valley"?

Is silicon a metal?
No — silicon is a non-metallic element, usually classified as a metalloid because it shows a mixture of metallic and non-metallic properties. Its ability to conduct electricity under some conditions but not others is exactly why it is the basis of computer chips.
Is sand made of silicon?
Mostly yes, in combined form: most sand is largely silica, a compound of silicon and oxygen, and silicon underlies most rock and sand on Earth. Pure elemental silicon is rarely found loose in nature and is refined from these minerals for uses such as chip-making.
