Silicon

Silicon is a type of element in chemistry. Its symbol is Si, and it has the number 14 on the periodic table. It's a hard, brittle solid that looks shiny and has a blue-grey color. Silicon is both a metal-like and a semiconductor material. On the periodic table, it belongs to group 14, where carbon is above it, and below it are elements like germanium, tin, lead, and flerovium.

Silicon is a chemical element found in the periodic table with the symbol Si and atomic number 14. It is a metalloid, which means it has properties of both metals and non-metals. Silicon is the second most abundant element in the Earth's crust after oxygen.
