what is iron made of?? help quik for homework due in tomorow?

Answer 1

Iron.
It is a metal usually refined from various forms of iron ore.
at. number 26
symbol Fe.
The melting point of iron is 1535°C, boiling point is 2750°C, specific gravity is 7.874 (20°C), with a valence of 2, 3, 4, or 6. Pure iron is chemically reactive and corrodes rapidly, especially in moist air or at elevated temperatures.

Answer 2

Iron is an element - on the periodic table of elements it's listed as 'Fe'. Being an element means it's not made from anything else, but it can react with other elements to make molecules - eg: with oxygen to make ferrous oxide.
However, like all elements it is made up of three types of smaller particles. Each element has a certain number of these - I'd say your homework is to find out how many go to make iron. No, I'm not going to tell you, and I don't think anyone on this board should either.

Answer 3

Iron is one of the natural elements of the periodic system, so it need not be "made". An element is never "made" of anything. (Therefore it is wrong to call water an element, because water consists of two parts hydrogen and one part oxygen.)
To get iron, iron ore must be found and then heated, so that the iron becomes liquid and flows out of the ore. Of course, used iron can also be melted to produce new iron - because iron is an element.
You can of course work on with iron, for example produce steel or make an alloy with another metal.

Answer 4

Whilst the other answers are correct in telling you where 'iron' comes from you cannot ask what is Iron made of as Iron is one element in a collection of about 142 elements that make up the chemical 'periodic table'.

Iron's chemical symbol is Fe (from the latin Ferric, Ferrous) and you can't break down an element, therefore iron is made out of iron and thats it. Like Shredded Wheat - nothing added and nothing taken away.

Answer 5

Your question is "what is iron made of?" Iron. Iron is a metallic element. Go to wikipedia, read up on it, and find it on the periodic-table (The article will tell you its atomic number and shwo its structure)

If you meant "from what is iron derived?" Iron ore. Again go to the article at wikipedia. There are many varieties of iron, and it (when combined with carbon and other materials) is used to make steel alloys of varying carbon content.

Hope the answer helped.

Answer 6

Iron Ore is mined from the ground , super heated and the molten residue poured of to become `Pig Iron` the basic form of iron .

Answer 7

Pig iron has 4% – 5% carbon and contains varying amounts of contaminants such as sulfur, silicon and phosphorus. Its only significance is that of an intermediate step on the way from iron ore to cast iron and steel.

Cast iron contains 2% – 4.0% carbon , 1% – 6% silicon , and small amounts of manganese. Contaminants present in pig iron that negatively affect the material properties, such as sulfur and phosphorus, have been reduced to an acceptable level. It has a melting point in the range of 1420–1470 K, which is lower than either of its two main components, and makes it the first product to be melted when carbon and iron are heated together. Its mechanical properties vary greatly, dependent upon the form carbon takes in the alloy. 'White' cast irons contain their carbon in the form of cementite, or iron carbide. This hard, brittle compound dominates the mechanical properties of white cast irons, rendering them hard, but unresistant to shock. The broken surface of a white cast iron is full of fine facets of the broken carbide, a very pale, silvery, shiny material, hence the appellation. In grey iron, the carbon exists free as fine flakes of graphite , and also, renders the material brittle due to the stress-raising nature of the sharp edged flakes of graphite. A newer variant of grey iron, referred to as ductile iron is specially treated with trace amounts of magnesium to alter the shape of graphite to sheroids, or nodules, vastly increasing the toughness and strength of the material.

Wrought iron contains less than 0.2% carbon. It is a tough, malleable product, not as fusible as pig iron. It has a very small amount of carbon, a few tenths of a percent. If honed to an edge, it loses it quickly. Wrought iron is characterised, especially in old samples, by the presence of fine 'stringers' or filaments of slag entrapped in the metal. Wrought iron does not rust particularly quickly when used outdoors. It has largely been replaced by mild steel for "wrought iron" gates and blacksmithing. Mild steel does not have the same corrosion resistance but is cheaper and more widely available.

Answer 8

Iron is an element so it is not made up of anything except iron molecules.
Who set you that homework? Your science teacher is a numpty!

Answer 9

You get iron by extracting it from Iron Ore.

Answer 10

Iron is an element by itself & is not a combination of other elements.
