Oxygen in the air, particularly combined with water, causes iron to rust, so iron turns into rust fairly quickly. Some iron alloys are rust resistant. While these are seldom found in nature, we do sometimes find nickel-iron meteorites that have not rusted away, which is the closest we come to finding metallic iron in nature.
One reason is, iron will naturally react with surrounding substances to form ores. Extracting the pure iron is often a difficult and expensive process. Also pure iron can corrode easily
A given type of Steel is one of several custom and precisely blended alloys of Iron, Carbon, and one or more other elements. The specific elements used and the percentages of each are carefully selected by metallurgists to give the final Steel the properties required for its application. There are many very different Steel alloys with very different properties, each designed for a certain group of applications.
The closest thing to Steel produced naturally is the Nickel-Iron alloy in metallic meteorites. But this alloy does not include enough Carbon to qualify as a true Steel.
Mechanical properties of pure iron are not convenient.
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.
yes
copper, silver and carbon are not real ores but could be found as pure elements: carbon as coal, or diamond. Silver as nuggets. Copper as native copper specimen. Iron is almost never found in the free elemental state, and should be extracted from iron ore, which is not iron, but mainly made of iron oxides.

A solid.
As rust is iron that is returning to a more stable state then most of the ions is iron
No such compound exists. If it did it would be iron VI oxide, but iron cannot reach such a high oxidation state. Perhaps you mean Fe2O3, iron III oxide.
Iron is rarely found in its native state the only known sources being Greenland where the iron occurs as nodules in basalt that erupted through beds of coal and two very rare nickel-iron alloys. Iron's symbol is Fe from the latin ferrum.
Two metals found in the outer core include: Iron and Nickel.
There are two Iron chlorides. Iron(II) chloride, in which iron is in +2 oxidation state, and Iron(III) chloride, in which iron is in +3 oxidation state.

First, this would be an compound, not an element. Second, it does not exist. If it did exist it would be iron VI oxide, but iron cannot reach such a high oxidation state. However, there is Fe2O3, which is iron III oxide.
