Uses and properties:

• A ductile, gray, relatively soft metal

• Moderately good conductor of heat and electricity

• Attracted by magnets and can be readily magnetized

• Pure metal is chemically very reactive and rusts readily in moist air, forming red-brown oxides

• There are three allotropic forms of iron, known as alpha (most stable), gamma, and delta

• Cheapest and most important of all metals making it the most commonly used metal

• Used to manufacture steel and other alloys

• Vital in the transportation of oxygen in the blood
