- Carbon is a nonmetal, and silicon is a metalloid. - Carbon and silicon have the same common electron configuration as s 2, p 2. But in silicon, the electrons are spread into the 3rd energy level, whereas in carbon it is only to the 2nd energy level.
Silicon dioxide (SiO2), silicon's most common compound, is the most abundant compound in the earth's crust. It commonly takes the form of ordinary sand, but also exists as quartz, rock crystal, amethyst, agate, flint, jasper and opal. Silicon dioxide is extensively used in the manufacture of glass and bricks. Silica gel, a colloidal form of silicon dioxide, easily absorbs moisture and is used as a desiccant. Silicon forms other useful compounds. Silicon carbide (SiC) is nearly as hard as diamond and is used as an abrasive.
