tl;dr:
Silicon is the 14th element on the periodic table. It's a metalloid, meaning it has properties of both metals and nonmetals, and is the second most abundant element in the Earth's crust, after oxygen.
Silicone, by contrast, is a synthetic polymer made up of silicon, oxygen and other elements, most typically carbon and hydrogen.
