Answer 2

Iron (IPA: /ˈʌɪə(r)n/) is a chemical element with the symbol Fe (Latin: ferrum) and atomic number 26. Iron is a group 8 and period 4 metal. Iron and nickel are notable for being the final elements produced by stellar nucleosynthesis, and thus the heaviest elements which do not require a supernova or similarly cataclysmic event for formation. Iron and nickel are therefore the most abundant metals in metallic meteorites and in the dense-metal cores of planets such as Earth.

==Notable Iron is believed to be the tenth most abundant element in the universe. Iron makes up 5% of the Earth's crust and is second in abundance to aluminium among the metals and fourth in abundance among the elements. Iron is also the most abundant element by mass, making up 35% of the mass of the Earth as a whole. The concentration of iron in the various layers of the Earth ranges from very high at the inner core to only a few percent in the outer crust.

Iron is a metal extracted from iron ore, and is almost never found in the free elemental state. In order to obtain elemental iron, the impurities must be removed by chemical reduction. Iron is used in the production of steel, an alloy or solid solution of different metals, and some non-metals, particularly carbon. The many iron-carbon allotropes, which have very different properties, are discussed in the article on steel.

Nuclei of iron have some of the highest binding energies per nucleon, surpassed only by the nickel isotope 62Ni. The universally most abundant of the highly stable nucleides is, however, 56Fe. This is formed by nuclear fusion in the stars. Although a further tiny energy gain could be extracted by synthesizing 62Ni, conditions in stars are not right for this process to be favoured, and iron abundance on Earth greatly favors iron over nickel, and also presumably in supernova element production. [citation needed] When a very large star contracts at the end of its life, internal pressure and temperature rise, allowing the star to produce progressively heavier elements, despite these being less stable than the elements around mass number 60, known as the "iron group". This leads to a supernova. Some cosmological models with an open universe predict that there will be a phase where as a result of slow fusion and fission reactions, everything will become iron.[citation needed]

Iron (as Fe2+, ferrous ion) is a necessary trace element used by all known living organisms. Iron-containing enzymes, usually containing heme prosthetic groups, participate in catalysis of oxidation reactions in biology, and in transport of a number of soluble gases. See hemoglobin, cytochrome, and catalase.

Answer 3

It depends on who you wish to define what a metal is. If you use the most commonly accepted idea of what a metal is, the Iron in all of its alloys would be the most commonly used. If you define metal as any element with only one electron in its outermost electron shell, then Hydrogen would by far be the most used metal --- everyone needs to drink it in its oxodized form (water (H2O)), everyone who drives a car uses it in many different ways from the acid in the battery to the hydrocarbons which lubricate and burn to make it run. Interestingly enough, Solid Hydrogen is a metal --- just really darn cold (just about absolute zero!).

Answer 4

Iron is the most used metal in the world, from the beginning of the civilisation till today.

Answer 5

Iron (Fe) is the most widely used metal in the world. It is the second most abundant metal in the Earth's crust.

The main iron ores are magnetite (Fe3O4), hematite (Fe2O3), limonite FeO(OH)·nH2O, Siderite FeCO3

Cheapest, most common, most useful, and most important metal. Used extensively for the making of steel and its associated alloys.

Products include cars, steel beams, rails, dishes, and bridges. Iron is the backstone of modern civilization.

Without it we would spin our clothes by hand and travel in wooden carts over dusty road

Answer 6

usually the most used metal in the world is IRON(indirectly) as in used as an alloy ,i.e steel .
steel and iron industries are booming due to the demand of it as it has a lot of tensile strength and can be used for construction purpose.
The next most used metal in the world might be gold or silver (Cox of women and their shopping habit [lol]).And the next used metal is copper(in wiring ) and aluminum(body parts of airplane).........................

Answer 7

Iron.

Answer 8

I do not know exactly, but am sure that it is iron used everywhere

Answer 9

Its either Iron or aluminum.

Answer 10

I would venture to guess Iron.
