Iron is one of the most plentiful elements. It comprises about 5.6% of the earth’s crust and almost all of the earth’s core.

The single largest use of iron is to make steel, an alloy of iron and a smaller amount of carbon. According to archaeological records from Anatolia, man has been producing steel for at least 4,000 years.

Iron is a transition metal.

Iron is not always magnetic! The allotrope (or form) or iron is ferromagnetic, yet if it is transformed to the b allotrope, the magnetism disappears even though the crystal lattice is unchanged.
