I detect another science homework here...I'm sure your teachers have twigged by now that the answers you are giving are not your own.If they have n't,they should...I'm telling...Nah-na-na-na-nah.

Iron is a metal, and being a metal, has properties that almost all metals have. It's grayish in color, is malleable, can be hammered into sheets, and has a relatively high melting point compared to some other nonmetals.
Lots of things are made from iron in one way or another. Anything made of steel--pots, pans, silverware, nails, screws, hammers, knives--originally started out as iron. Steel is an alloy made from iron and carbon (sometimes chromium and nickel too), and is thus a product of iron. Iron can also be used for decorative purposes, and is usually called wrought iron when it is. You can make fences and fancy gates and things like that from wrought iron.
Iron is fairly strong and flexible, as well as relatively readily available. It can bend without snapping, yet can still support quite a bit of weight. Iron ore isn't a rarity, either, so it's fairly cheap.
Probably a combination of all the answers to the previous question. The fact that it's strong, flexible, and cheap trumps just about every other metal. You can find metals that are stronger (tungsten or titanium, for example), but both are considerably more expensive than iron is.

Too general.
1. Properties. Chemical? Mechanical?
2. Just about everything! Pots, Pans, Baths, Castings, Forgings, you name it!
Different Properties can be fed into the metal at the time of it's 'melting'. Chemically, for example, if you add certain elements - aluminium, carbon, sulphur, phosphorus etc etc, it can do many different things to the metal. Make it hard, brittle, malleable...all sorts! Look up 'Effects of Alloying Elements in Steel' on the internet. You can see how the adding of or denial of a chemical into the metal can affect it.
Mechanically, you can change properties by heat treatment or 'working' the material in a certain way. The material can be melted, left to cool, reheated, left to cool again and this can again do all sorts to the material. Make it rock hard, or very soft for example.
I am being extremely basic here but this is the basis of all metal worldwide.
It will need to have chemicals put into it. Iron obviously has lots of Iron ore which is melted, good properties added, bad ones eliminated and hey presto, you have a 'Grade of material' which is usually manufactured to a 'Standard'. Each country tend to have it's own, but very similar 'Recipe Book' of standards. The Uk is 'BS'. The USA is 'ASTM', Japan is 'JIS', Germany is 'DIN'.
Basically, they will all cook a similar cake.
Adding elements and taking them away affects the material in many ways - far too many to mention, but a nice easy one is Stainless Steel. You can compare this to 'iron' as all metals are made in a 'similar' way. They are almost always 'melted' and Stainless has fantastic properties that make it...well stainless (almost!) for one thing. It is a tough, hard wearing material that keeps it's shape well. Car bodies for example. Iron is also hard wearing and can be 'cast' or made into many shapes. (Think of the old cast baths).
I don't think you can ever say that one metal is better than another. Given any application, there is a metal for it. Iron rusts easily for example, especially in salty areas. So does Stainless steel, but less so. There is a grade of metal that has virtually no corrosion in seawater at all but as you would expect it is extremely expensive! We could not build baths out of it - it would probably cost more than my house!
If you need any more info, contact me.

Atomic Number :26
Atomic Symbol: Fe
Atomic Weight: 55.847
Electron Configuration: [Ar]4s23d6
History :(Anglo-Saxon, iron; L. ferrum) Iron was used prehistorically:
Genesis mentions that Tubal-Cain, seven generations from Adam, was "an instructor of every artificer in brass and iron."
A remarkable iron pillar, dating to about A.D. 400, remains standing today in Delhi, India. This solid shaft of wrought iron is about 7 1/4 m high by 40 cm in diameter. Corrosion to the pillar has been minimal although it has been exposed to the weather since its erection.
Production: Iron is a relatively abundant element in the universe. It is found in the sun and many types of stars in considerable quantity. Its nuclei are very stable. Iron is a principal component of a meteorite class known as siderites and is a minor constituent of the other two meteorite classes. The core of the earth -- 2150 miles in radius -- is thought to be largely composed of iron with about 10 percent occluded hydrogen. The metal is the fourth most abundant element, by weight that makes up the crust of the earth.
The most common ore is hematite, which is frequently seen as black sands along beaches and banks of streams.
Properties: The pure metal is very reactive chemically and rapidly corrodes, especially in moist air or at elevated temperatures. It has four allotropic forms or ferrites, known as alpha, beta, gamma, and omega, with transition points at 700, 928, and 1530C. The alpha form is magnetic, but when transformed into the beta form, the magnetism disappears although the lattice remains unchanged. The relations of these forms are peculiar. Pig iron is an alloy containing about 3 percent carbon with varying amounts of Sulfur, Silicon, Manganese, and Phosphorus.
Iron is hard, brittle, fairly fusible, and is used to produce other alloys, including steel. Wrought iron contains only a few tenths of a percent of carbon, is tough, malleable, less fusible, and has usually a "fibrous" structure.
Carbon steel is an alloy of iron with small amounts of Mn, S, P, and Si. Alloy steels are carbon steels with other additives such as nickel, chromium, vanadium, etc. Iron is a cheap, abundant, useful, and important metal.
Isotopes :Common irons is a mixture of four isotopes. Ten other isotopes are known to exist.
Uses Iron is a vital constituent of plant and animal life and appears in hemoglobin.
Taconite is becoming increasingly important as a commercial ore. The pure metal is not often encountered in commerce, but is usually alloyed with carbon or other metals.
Cost :Low

THE TWO CODES IN IRON
Iron is one of the four most abundant elements in the world and for ages, it has been one of the most vital metals for mankind. The verse referring to iron is as follows:
"…And We sent down iron in which there lies great force and which has many uses for mankind." (Surat al-Hadid: 25)
This verse incorporates two very interesting mathematical codes.
"Al-Hadid" (Iron) is the 57th surah of the Qur’an. The numerical value (in the "Abjad" system of Arabic in which each letter has a numerical value) of the letters of the word "Al-Hadid" is the same: 57.
The numerical value (Abjad) of the word "Hadid" (iron) alone, without the definite article "al", is 26 and 26 is the atomic number of iron.

Do a google search on it.
Also go to http://www.billnye.com And it should have some info there for you.
Quit asking people for the answers to your homework. Put the XBOX controls down and do a little reading and maybe you will learn something.
The reason this user won't look for themself is people like Lary always there ready to cut and paste the answers.

I don't know its properties.But i am a welder and it is strong flexible to some extent and you can make almost any thing out of it .
