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.
