WebA covalent crystal contains a three-dimensional network of covalent bonds, as illustrated by the structures of diamond, silicon dioxide, silicon carbide, and graphite. Graphite is an exceptional example, composed of planar sheets of covalent crystals that are held together in layers by noncovalent forces. WebCovalent Bonds. A covalent bond is a crystal structure where the electrons do not exit their orbits, as the name implies. Electrons, on the other hand, are shared by two atoms. Every two neighbouring atoms are connected by a common electron in this way. The bonded atoms share an additional electron with the atoms next to them, and so on.
