what happens when iron reacts with oxygen and water?
water splitting
pristine and smooth pure iron surfaces are mirror-like silvery-gray. however, iron reacts readily with oxygen and water to give brown to black hydrated iron oxides, commonly known as rust. unlike the oxides of some other metals, that form passivating layers, rust occupies more volume than the metal and thus flakes off, exposing fresh surfaces for corrosion.

all the halogens are known to react with sodium to form sodium fluoride, sodium chloride, sodium bromide, sodium iodide, and sodium astatide. heated sodium's reaction with halogens produces bright-orange flames. sodium's reaction with chlorine is in the form of:









































iron reacts with fluorine, chlorine, and bromine to form iron(iii) halides. these reactions are in the form of:









































however, when iron reacts with iodine, it forms only iron(ii) iodide.
