Answer:
It combines vigorously with chlorine on mild heating and also with a variety of other nonmetals, including all of the halogens, sulfur, phosphorus, boron, carbon, and silicon (the carbide and silicide phases play major roles in the technical metallurgy of iron). Metallic iron dissolves readily in dilute mineral acids.
Explanation:
Iron is the chemical species that is the most used metal and is often found attached to the chlorine element.
Iron metals react with many elements and are an abundant element in the Earth's crust. It combines with the chlorine element when subjected to mild heating.
Along with chlorine it also reacts with halogen groups, carbon, sulfur, silicon, etc. This application is used in the metallurgy of iron.
Therefore, iron is joined to chlorine.
