3 chemical properties of oxygen

One of the chemical properties of iron is that it easily gets oxidized in open air, and this is why many compounds of iron (II) get oxidized into iron (III). (credit a: modification of work by Tony Hisgett; credit b: modification of work by “Atoma”/Wikimedia Commons) To identify a chemical property, we look for a chemical change.
