Why is silicon dioxide made up of atoms?
Silicon dioxide is an atomic crystal. In silicon dioxide crystal structure, each silicon atom combines 4 oxygen atoms, and each oxygen atom combines 2 silicon atoms, which explains why the chemical formula of silicon dioxide is SiO2.
But each oxygen atom is on a regular tetrahedron centered on another silicon atom, that is, each oxygen atom is shared by two silicon oxygen tetrahedra
In the case of crystalline silica and other carbon atoms and carbon atoms around the bond and diamond crystals in the connection into four oxygen atoms and around each silicon atom is the same. The four oxygen atoms and around each silicon atom to form a tetrahedron.
