What is the most abundant element in the Earth's crust?
Iron makes up 5 percent of Earth ’s crust and is second in abundance to aluminum among the metals and fourth in abundance behind oxygen, silicon, and aluminum among the elements. Iron, which is the chief constituent of Earth’s core, is the most abundant element in Earth as a whole (about 35 percent) and is relatively plentiful in the Sun and other stars. In the crust the free metal is rare, occurring as terrestrial iron (alloyed with 2–3 percent nickel) in basaltic rocks in Greenland and carbonaceous sediments in the United States (Missouri) and as a low-nickel meteoric iron (5–7 percent nickel), kamacite. Nickel-iron, a native alloy, occurs in terrestrial deposits (21–64 percent iron, 77–34 percent nickel) and in meteorites as taenite (62–75 percent iron, 37–24 percent nickel). (For mineralogical properties of native iron and nickel-iron, see native elements [table].) Meteorites are classified as iron, iron-stone, or stony according to the relative proportion of their iron and silicate-mineral content. Iron is also found combined with other elements in hundreds of minerals; of greatest importance as iron ore are hematite (ferric oxide, Fe 2 O 3 ), magnetite (triiron tetroxide, Fe 3 O 4 ), limonite (hydrated ferric oxide hydroxide, FeO (OH)∙ n H 2 O), and siderite (ferrous carbonate, FeCO 3 ). Igneous rocks average about 5 percent iron content. The metal is extracted by smelting with carbon ( coke) and limestone.

What temperature does alpha iron become?
At 910 °C (1,670 °F) there is a transition to paramagnetic alpha iron, which is also body-centred cubic in structure. Below 773 °C (1,423 °F), alpha iron becomes ferromagnetic (i.e., capable of being permanently magnetized), indicating a change in electronic structure but no change in crystal structure.
How much carbon is in iron?
These modify its properties, from hard and brittle cast irons containing up to 4 percent carbon to more malleable low-carbon steels containing less than 0.1 percent carbon.
Where did iron come from?
Iron nuclei were made later in stars and formed atoms and these are the true origins of iron. When our Earth separated from its parent star, it also inherited its core from the iron present in the star (so effectively, iron was never created on Earth). This is the first source.
When was iron discovered?
This is the oldest source of information about the origins of Iron, revealed approximately fourteen hundred years ago (as radiocarbon dating of Quran’s oldest scripts show), before science understood the origins of iron and other elements.
What is the core of the Earth made of?
From the scientific perspective, Earth’s core is made of iron, as inherited from the original star the Earth and solar system were made from. But it could not be used by humans for their uses, since there was no iron on the surface.
How did iron ore turn into wrought iron?
Introduction. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process.".
How did hammermen make wrought iron bars?
Hammermen completed the wrought iron bars by forging them between the hammer and the anvil. The loop was hammered into a block or "bloom". From there the bloom was hammered systematically from its middle out towards one end. The bar would be re-heated numerous times in the "chafery hearth" to maintain a welding heat.
Why did the founders start a fire at the bottom of the furnace?
A wood fire was started at the bottom of the furnace to dry out the mortar that was between the new lining stones and brick. Gradually at first, charcoal, iron ore, and gabbro were charged into the top of the furnace in layers by the furnace fillers. The "burden" as it was called, was carefully managed by the founder.
What was the role of the founder in the furnace?
The founder also was responsible for managing air flow from the bellows. The burden was held in place above the crucible (where the molten iron was collected) at the bottom of the furnace by a narrowing of the furnace lining called the "boshes". Air was pumped into the furnace above the crucible but below the boshes.
How do elements form together?
The elements form together inside a star during fusion. When the supernova occurs, the iron fragments are blasted into the space. This is how Iron came to Earth millions of years ago. You can see the image below of a 20 Solar Mass ( M o) star. Answer link.
Why does an explosion happen?
The explosion results because the star has burned off all if its fuel, and its gravity is so powerful that only the iron core is left. For iron and heaver elements, fusion is no longer an option. The power of the gravity can only be released by fission, or the immediate breakdown of the iron in an explosion.
Where is iron found on Earth?
Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron ...
When did iron ore form?
Nearly all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters.
What is the primary use of iron ore?
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.
Where does iron come from?
The word ferrum itself possibly comes from the Semitic languages, via Etruscan, from a root that also gave rise to Old English bræs " brass ". The English word iron derives ultimately from Proto-Germanic *isarnan, which is also the source of the German name Eisen and Dutch ijzeren. It was most likely borrowed from Celtic *isarnon, which ultimately comes from Proto-Indo-European * is- (e)ro- "powerful, holy" and finally * eis "strong", referencing iron's strength as a metal. Kluge relates *isarnon to Illyric and Latin ira, 'wrath'). The Balto-Slavic names for iron (e.g. Russian железо [ zhelezo ], Polish żelazo, Lithuanian geležis) are the only ones to come directly from the Proto-Indo-European *ghelgh- "iron". In many of these languages, the word for iron may also be used to denote other objects made of iron or steel, or figuratively because of the hardness and strength of the metal. The Chinese tiě ( traditional 鐵; simplified 铁) derives from Proto-Sino-Tibetan *hliek, and was borrowed into Japanese as 鉄 tetsu, which also has the native reading kurogane "black metal" (similar to how iron is referenced in the English word blacksmith ).
How is iron made?
For a few limited purposes when it is needed, pure iron is produced in the laboratory in small quantities by reducing the pure oxide or hydroxide with hydrogen, or forming iron pentacarbonyl and heating it to 250 °C so that it decomposes to form pure iron powder. Another method is electrolysis of ferrous chloride onto an iron cathode.
How does the body regulate iron?
Iron uptake is tightly regulated by the human body, which has no regulated physiological means of excreting iron. Only small amounts of iron are lost daily due to mucosal and skin epithelial cell sloughing, so control of iron levels is primarily accomplished by regulating uptake. Regulation of iron uptake is impaired in some people as a result of a genetic defect that maps to the HLA-H gene region on chromosome 6 and leads to abnormally low levels of hepcidin, a key regulator of the entry of iron into the circulatory system in mammals. In these people, excessive iron intake can result in iron overload disorders, known medically as hemochromatosis. Many people have an undiagnosed genetic susceptibility to iron overload, and are not aware of a family history of the problem. For this reason, people should not take iron supplements unless they suffer from iron deficiency and have consulted a doctor. Hemochromatosis is estimated to be the cause of 0.3 to 0.8% of all metabolic diseases of Caucasians.
What is the solution of ferropericlase?
Ferropericlase (Mg,Fe)O, a solid solution of periclase (MgO) and wüstite (FeO), makes up about 20% of the volume of the lower mantle of the Earth, which makes it the second most abundant mineral phase in that region after silicate perovskite (Mg,Fe)SiO#N#3; it also is the major host for iron in the lower mantle. At the bottom of the transition zone of the mantle, the reaction γ- (Mg,Fe)#N#2[SiO#N#4] ↔ (Mg,Fe) [SiO#N#3] + (Mg,Fe)O transforms γ-olivine into a mixture of silicate perovskite and ferropericlase and vice versa. In the literature, this mineral phase of the lower mantle is also often called magnesiowüstite. Silicate perovskite may form up to 93% of the lower mantle, and the magnesium iron form, (Mg,Fe)SiO#N#3, is considered to be the most abundant mineral in the Earth, making up 38% of its volume.
What are the oxidation states of iron?
Chemically, the most common oxidation states of iron are iron (II) and iron (III). Iron shares many properties of other transition metals, including the other group 8 elements, ruthenium and osmium. Iron forms compounds in a wide range of oxidation states, −2 to +7.
Why is iron acquisition a problem for aerobic organisms?
Thus, these organisms have developed means to absorb iron as complexes, sometimes taking up ferrous iron before oxidising it back to ferric iron. In particular, bacteria have evolved very high-affinity sequestering agents called siderophores.
How many isotopes does iron have?
Iron has four stable isotopes: 54 Fe (5.845% of natural iron), 56 Fe (91.754%), 57 Fe (2.119%) and 58 Fe (0.282%). 20-30 artificial isotopes have also been created. Of these stable isotopes, only 57 Fe has a nuclear spin (− 1⁄2 ). The nuclide 54 Fe theoretically can undergo double electron capture to 54 Cr, but the process has never been observed and only a lower limit on the half-life of 3.1×10 22 years has been established.
Overview
Characteristics
At least four allotropes of iron (differing atom arrangements in the solid) are known, conventionally denoted α, γ, δ, and ε.
The first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure. As it cools further to 1394 °C, it cha…
Origin and occurrence in nature

Chemistry and compounds
Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s. Iron is sometimes considered as a prototype for the entire block of …
History
Iron is one of the elements undoubtedly known to the ancient world. It has been worked, or wrought, for millennia. However, iron objects of great age are much rarer than objects made of gold or silver due to the ease with which iron corrodes. The technology developed slowly, and even after the discovery of smelting it took many centuries for iron to replace bronze as the metal of choi…
Symbolic role
Iron plays a certain role in mythology and has found various usage as a metaphor and in folklore. The Greek poet Hesiod's Works and Days (lines 109–201) lists different ages of man named after metals like gold, silver, bronze and iron to account for successive ages of humanity. The Iron Age was closely related with Rome, and in Ovid's Metamorphoses
Production of metallic iron
