You think probable to oxygen and water (H2O).
It is relatively rare, you will not usually see it on a daily basis.

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.
Bromine is an element, a very very reactive element. At standard temperature and pressure it is a brown colored liquid, as seen in the center vial in the image above. However bromine is so reactive that you will never see it in its elemental form in daily life, it is most commonly is found in compounds called bromide salts.

aluminum itself is an element, but most products made of aluminum are actually an aluminum alloy.both aluminum and aluminum alloys have a thin glassy (sometimes colored) coating of aluminum oxides, which protects the actual metal surface. This coating is a compound or mixture of compounds and elements.Now wasn't that complicated?
Oxygen and nitrogen are breathed daily. Sodium and chloride are usually ingested daily. (salt)
It all depends with the amount of the annual or daily compounding. In most cases it is however the daily compounding that pays more than the annual compounding.
sometimes or in some cases. and it depends.

Everything. !!!! You as a human being are an organic compound (electro-chemical polymer). The food you eat is an organic compound.
