- 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. Much of the silicon and oxygen in the Earthâs crust is present as the compound silicon dioxide also known as silica. Silicon dioxide has a giant covalent structure.Part of this structure is shown in the diagram-oxygen atoms are shown as red, silicon atoms shown as brown:hese properties result from the very strong covalent bonds that hold the silicon and oxygen atoms in the giant covalent structure. Silicon dioxide is found as quartz in granite, and is the major compound in sandstone. The sand on a beach is made mostly of silicon dioxide. Page: 1  1. 2  2. 3  3. 4  4.
