Iron

IRON                  Iron in its pure state is soft, tractile and bendable (that can be stretched, drawn or beat fragile with off breaking ((Websters Dictionary, 419, 1988)) with a surdness of 4-5. It is easily magnetize at room temperatures and this property disappears when heated above 790 degrees Celsius.. alloy smoothing campaign occurs in a free state in unaccompanied a few localities, notably Green line up down (Encarta, 1996).

Iron is a active metal and will combine with halogens, carbon, etc. It has an atomic weight 55.847, its atomic number is 26, its precise gravity is 7.86, its melting point is 1535 degrees Celsius, and its boiling point is 3000 degrees Celsius. It ruin in oxygen forming ferrous oxide. When receptive to moist air, iron becomes corroded, forming a reddish - brown, flaky, hydrated ferrous oxide, commonly cognise as rust. (Encarta, 1996)         Iron is formed in shallow seas.

It comes expose of the water and collects on the sea foundation. This creates an submersed determine. This process occurs everyplace billions of years. Through plate movement the self-coloured sea floor is eventually moved up let out of the water. Once out of the wat! er, the iron has formed a land deposit. The biggest iron deposit in the United States is in the broad Lakes. Northern atomic number 25 is often called the Iron Range. There ar two ways iron deposits are located.
