Astatine
When a halogen, like chlorine, reacts with iron, the halogen will displace the iron from its compound to form a new compound. For example, when chlorine gas reacts with iron, it forms iron chloride. This process is a redox reaction, where the halogen gains electrons from the iron.
The group sevens non-metals get less reactive the further down the table they fall, making fluorine the most reactive and iodine least reactive. So based on this i would say that fluorine reacts fastest with iron (:
You could use spectroscopy as a definite method, or you could use an oxidizing agent that reacts with O2 (Oxygen), such as Iron, Nitric Acid, or halogen compounds.
oxygen
Iron reacts with oxygen to form Fe2O3 also known as rust. Oxygen requires two electrons to fill it's valence shell so iron loses electrons.

Iron(III) chloride typically reacts slowest with sodium cyanide. This reaction is used in the laboratory to detect the presence of cyanide ions in a solution.

A salt
When a halogen reacts with a metal, an ionic compound called a metal halide is formed. The metal donates its electrons to the halogen, resulting in the formation of a stable compound. This reaction usually involves the transfer of electrons from the metal to the halogen.
Halogen reacts with metals to form salts. For example, sodium reacts with chlorine to form sodium chloride (table salt).
Reacts with a halogen to form a salt.
Reacts with a halogen to form a salt.
When a halogen reacts with a metal, an ionic compound called a metal halide is formed. This compound is formed by the transfer of electrons from the metal to the halogen, resulting in the formation of a positively charged metal ion and a negatively charged halide ion. The exact formula of the metal halide depends on the specific metal and halogen involved in the reaction.
Iron oxide is formed when iron reacts with oxygen, commonly known as rust.
oxygen reacts with iron and forms rust Oxygen reacts with iron to form iron oxide.
Carbon monoxide reacts with iron oxide to produce iron and carbon dioxide in a process known as reduction.
