Aluminium oxide is a compound.
It is an element, and can be found on the Periodic Table as Al.
Ferric oxide, an alternative name for iron (III) oxide, is a compound.
Aluminium is itself an element. By itself, Aluminium cannot be a compound because a compound consists of two or more elements. Similarily, mixtures are two or more elements that are combined, but retain their chemical identities. If aluminium were part of an alloy (a combination of metals, which is what most aluminium products you see daily are actually made of) then it would be considered a mixture. To summarize: if you're only talking about Aluminium alone, then it is an element.
Lime is a compound.
