Ranked between metals and non-metals in the periodic table, silicon (Si) belongs to the metalloids family. Silicon is the most abundant element in the Earth's crust after oxygen (O) but it does not naturally exist in a free state on Earth. Commonly found in the form of oxides, it is one of the main components of clay, granite, quartz and sand.
