Gold is much less reactive than iron. Over time iron reacts with our oxygen-rich atmosphere, especially if moisture is present. So the form in which iron is found in nature is chemically similar to rust.
Gold on the other hand is a noble metal, it hardly reacts with anything. Even most strong acids will not corrode it.
This is because metals like gold lie at the bottom in the activity series so they are less reactive and are found in the free state, whereas, metals like aluminium, zinc, etc. are found on the top of the activity series so they are highly reactive and are found in the form of compounds.

Because gold is noble, what means that if it forms a compound, which is very unlikely, that compound spontaneously breaks into free gold
Yes. copper is one of the elements that may, with luck, be found in the native state.
Only a few metals are found in the free state, generally metals react to form for example oxides, sulfides which then may further react. Some found free are gold silver copper and platinum. All of these are relatively unreactive
Gold is found ONLY in free state, since it is noble, does not tend to link. Moreover, its compounds, if were present in nature, would decompose under heat, light - to free gold
Ag(silver), Au(gold), Pt(platinum), Cu(copper) are found in free state
iron,silver,and gold
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.

Atoms cannot exist in a free state on their own, but can exist in a free state as molecules.

Sodium (Na) is a highly reactive element so it cannot be found in free state but we can have it in compound form like NaCl.
Sodium, being a reactive element In group 1, cannot be found as element in nature. One of its common compounds is rock salt.
