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.
Iron does not occur in its free state in nature due to its high reactivity. It is typically found in minerals such as hematite, magnetite, and siderite, which must be processed to extract the elemental iron.
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.
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.
Iron's natural state in the ground is typically found in the form of iron ores such as hematite, magnetite, and siderite. These ores are mined and processed to extract iron metal for various applications.
Iron in the body is typically found in iron protein complexes because it helps regulate iron levels and prevent free iron from causing damage to cells through oxidative stress. These complexes also assist in transporting iron throughout the body and delivering it to cells where it is needed for various physiological processes.

A solid.
Iron is commonly found in two main forms: iron (II) and iron (III). Iron (II), or ferrous iron, typically has a 2+ oxidation state, while iron (III), or ferric iron, typically has a 3+ oxidation state. These forms of iron can be found in various minerals, ores, and biological systems.

Iron nitrate is a compound formed by the reaction of iron and nitric acid and is typically found in the form of salts. It is not a state in and of itself but rather a chemical compound that can exist as a solid (e.g. iron(III) nitrate) or in solution.
Iron's natural state in the ground is typically found in the form of iron ores such as hematite, magnetite, and siderite. These ores are mined and processed to extract iron metal for various applications.
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.
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.
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.
