WebDifferences. As a result, simple covalent substances generally have low melting/boiling points. Giant covalent substances, such as diamond, contain many strong covalent bonds in a 3D lattice structure. The connection between the structure and the way a product behaves, is central to materials science and product engineering and design. WebSome covalently bonded substances have giant covalent structures, such as diamond and silicon dioxide. The covalent bonds in molecules and giant structures can be represented in the following forms (for ammonia: two types of dot-cross; chemical structure; ball stick) 4.2.1.1 Chemical bonds WebChemical Bonding (Covalent, Ionic and Metallic) Worksheets.
