Reaction of iron with the halogens. Iron reacts with excess of the halogens F2, Cl2, and Br2, to form ferric, that is, Fe(III), halides. This reaction is not very successful for iodine because of thermodynamic problems. The iron(III) is too oxidizing and the iodide is too reducing.
Iron is the fourth most common element in the Earthâs crust, but pure iron is relatively soft and flexible. Steel is an alloy of iron mixed with low levels of other elements, such as carbon, silicon and manganese.
