A pure compound substance is one that is composed only of elemental equivalent atoms. Table salt, for example, is composed of sodium and chlorine atoms ionically bound to each other. That isn't exactly "pure" since it requires to atoms...so how about carbon? Carbon can exist in many states- it can be "locked" in, a la diamond, where the crystaline structure is too strong for normal molecules to break, or it can be graphite (also made of carbon), wherepon the simple act of friction causes layers of this atomic structure to stick.
