WebFor example, take a look at the Lewis diagram for ethene, C 2 H 4. Ethene consists of two carbon atoms joined by a double covalent bond. Each carbon atom is also bonded to two hydrogen atoms with single covalent bonds. Carbon atoms are much bigger than hydrogen atoms - they have an extra electron shell. WebAn example of a covalent compound is ammonia. The chemical formula of ammonia is NH 3 _3 3 start subscript, 3, end subscript, which tells us that in a single molecule of ammonia, there is one nitrogen atom, and three hydrogen atoms. The structure of a covalent compound can be depicted through space-filling models as well as ball-and-stick models.
