¨ Silicon dioxide (SiO2), also known as silica, is a covalent compound that has a network solid structure. In this structure, each silicon atom is covalently bonded to four oxygen atoms, while each oxygen atom is bonded to two silicon atoms. This arrangement gives rise to a three-dimensional network of atoms that extends throughout the entire solid.
¨ The tetrahedral geometry of the SiO4 units in the silica network allows each silicon atom to be surrounded by four oxygen atoms, with each oxygen atom sharing two electrons with the silicon atom to form a strong covalent bond.
