Say what? History and Uses: Archaeological evidence suggests that people have been using iron for at least 5000 years.
Huge amounts of iron are used to make steel, an alloy of iron and carbon. In addition to helping build the world around us, iron helps keep plants and animals alive.

Background Iron is one of the most common elements on earth. Nearly every construction of man contains at least a little iron. It is also one of the oldest metals and was first fashioned into useful and ornamental objects at least 3,500 years ago. Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found in minerals formed by the combination of iron with other elements. Iron ore is converted into various types of iron through several processes. History Historians believe that the Egyptians were the first people to work with small amounts of iron, some five or six thousand years ago.
Tools and weapons brought back to Europe from the East were made of an iron that had been melted and cast into shape. Raw Materials The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. William S. Extraction. Changing Materials - Iron. Bookmarked webpages about iron "Iron (Fe) is the second most common metal on Earth, and the most widely-used metal by humans.
It is element 26, a transition metal in Group 8. Its symbol is Fe, from the Latin word for iron, ferrum. Its atomic number is 26 and its mass number is 55.85.It is used a lot because it is very strong and cheap. Iron is the main ingredient used to make steel.

The Periodic Table of Videos - University of Nottingham. Visual Elements Periodic Table. WebElements Periodic Table of the Elements. Dynamic Periodic Table. Metal. A metal (from Greek "μέταλλον" – métallon, "mine, quarry, metal"[1][2]) is a solid material (an element, compound, or alloy) that is typically hard, opaque, shiny, and features good electrical and thermal conductivity.
Metals are generally malleable—that is, they can be hammered or pressed permanently out of shape without breaking or cracking—as well as fusible (able to be fused or melted) and ductile (able to be drawn out into a thin wire).[3] 91 of the 118 elements in the periodic table are metals. The meaning of "metal" differs for various communities. For example, astronomers use the blanket term "metal" for convenience to collectively describe all elements other than hydrogen and helium (the main components of stars, which in turn comprise most of the visible matter in the universe). Structure and bonding hcp and fcc close-packing of spheres The atoms of metallic substances are closely positioned to neighboring atoms in one of two common arrangements.
