Iron reacts with oxygen in air to for rust.
In damp air, the primary substances needed for iron to react are moisture (water vapor) and oxygen. The presence of water facilitates the formation of electrolytic solutions, which can accelerate the oxidation process of iron. This leads to corrosion, commonly seen as rust (iron oxide), when iron reacts with both oxygen and water. Additionally, impurities in the air, such as salt or pollutants, can further enhance this reaction.
Iron can react with water in the presence of air and form rust.
Iron left damp and exposed to oxygen is prone to rust as the iron, water and air react to oxidize iron at the surface of the pan. Drying an iron skillet immediately after washing helps to protect the skillet from rusting.

When iron reacts with air, they form ferric oxide.
Hydrochloric acid can react with iron in the absence of air to produce iron chloride and hydrogen gas. The reaction between hydrochloric acid and iron is a chemical reaction that does not require oxygen from the air.
Halogens react with air to form metal halides. For example, chlorine will react with iron to form iron(III) chloride. Halogens are highly reactive and will readily form compounds with many elements in the air.
Bromine does not react with air because it is not possible. It is a non reactant element.
Oxygen
I think it's rust (iron oxide or hydrated iron oxide) because when iron reacts with water and air, rust is the product. At least that's what we were taught in science today!
One example of an element that fits this description is noble gas. Noble gases such as helium, neon, and argon do not react with water and can react violently with air when exposed to certain conditions.
Iron is itself an element, symbolized as Fe.
