Elements and Compounds. Looking at the left side of the chart, we can see that a pure substance can be either an element or a compound. For example, we mentioned that oxygen is a compound as it consists of two oxygen atoms connected by covalent bonds. Another example can be water where two hydrogen atoms are connected to an oxygen atom.

Naming Acids. Simple covalent compounds that contain hydrogen, such as HCl, HBr, and HCN, often dissolve in water to produce acids. These solutions are named by adding the prefix hydro- to the name of the compound and then replacing the suffix -ide with -ic.For example, hydrogen chloride (HCl) dissolves in water to form hydrochloric acid; hydrogen bromide (HBr) forms …
