Elements are particles with the same #"atomic number, Z"#.

Explanation:

And what is #Z# but the number of positively charged, massive particles that comprise (part) of the element's nucleus.

#Z=1, H; Z=2, He; Z=3, Li; ..........Z=24, Cr....#

Compounds are mixtures of elements that are chemically bound together. And mixtures are simply 2 or more elements and compounds THAT ARE NOT chemically bound together. The best example of a mixture is the air we breathe, which comprises elemental dinitrogen, and dioxygen, and the compound, carbon dioxide.
