Iron and steel - Introduction to their science, properties, uses

Pure iron is too soft and reactive to be of much real use, so most of the "iron" we tend to use for everyday purposes is actually in the form of iron alloys: iron mixed with other elements (especially carbon) to make stronger, more resilient forms of the metal including steel. Broadly speaking, steel is an alloy of iron that contains up to ...

Chemistry for Kids: Elements - Iron

The Earth's core is mostly made up of an iron-nickel alloy. Iron also makes up about 5% of the Earth's crust where it is the fourth most abundant element. Because iron oxidizes when it comes into contact with air, most of the iron that is found on the surface of the Earth is in iron oxide minerals such as hematite and magnetite.

IRON. Iron is the most abundant metal on Earth. But like most metals, getting to it is tricky, because its very rarely found in a pure state in nature. It most commonly exists in iron oxidesmolecules composed of iron and oxygen, which are found mixed with rock in iron ore. To get the iron, you have to get rid of the oxygen and the rock.
