Formation of Ionic Iron Oxide
Formation of Ionic Iron Oxide

Steel wool burns in air with a very bright white light, giving off a large amount of energy, and white smoke with is iron oxide in very fine particles. The steel wool changes color to a more gray appearance which is the iron oxide. It is proven that the steel wool has changed into a compound because you can no longer ignite the steel wool after it has burned.

The Octet Rule is the basis for the predictions about the charges on ions. A compound is not stable unless the number of electrons which are lost equals those gained. The electrons gained or lost on each atom may be different. The exchange of electrons continues until there are no left over electrons and no empty spots. This sometimes results in several atoms being required. The subscripts are written to show how many of each kind of atom is involved.

In Australia, storms whipping red iron oxide dust into the atmosphere of city centers has revealed that iron oxide can cause breathing problems and exacerbate asthma, allergies and sinus infections. The iron oxide itself isn t so dangerous as the plant pollen and material it attracts to it; this material can cause serious and potentially life-threatening allergic reactions.

Iron oxide is frequently used to make magnets, and these have been linked to a variety of health problems. The most common danger of small iron oxide magnets is that they might get swallowed. Two magnets inside the digestive tract can bind together between intestinal walls, creating a blockage that can have serious or even deadly medical repercussions. This is especially dangerous with infants and toddlers, who can easily swallow small magnets.
