Can pure substances only be compounds?

Ostensibly, compounds contain more than one type of material. Yet both compounds and elements are considered pure substances. A mixture is created when substances combine but no chemical reaction occurs. In general, a mixture can be separated into its original components, while a pure compound cannot.

Which is the best description of a mixture?
