Why can gold be found as the uncombined metal?
Gold is easily reduced, so oxygen continuously converts its compounds into pure metal.
Gold is less dense, so it separates naturally from all other elements.
Gold is very unreactive, so it barely reacts with other elements.
Gold is very reactive, so it quickly displaces other metals from their compounds.
