Iron

IRON                  Iron in its pure state is soft, tensile and bendable (that can be stretched, drawn or hammer 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.. coat smoothing campaign occurs in a free state in unaccompanied a few localities, notably Green sheer down (Encarta, 1996).

Iron is a active metal and will fuse with halogens, carbon, etc. It has an atomic weight 55.847, its atomic nu mber is 26, its precise gravity is 7.86, its melting point is 1535 degrees Celsius, and its boiling point is 3000 degrees Celsius. It burn down in oxygen forming ferrous oxide. When receptive to moist air, iron becomes corroded, forming a reddish - brown, flaky, hydrated ferrous oxide, commonly know as rust. (Encarta, 1996)         Iron is formed in shallow seas. It comes start of the water and collects on the sea unwraprage. This creates an submersed lodge. This process occurs over billions of years. Through plate movement the self-coloured sea floor is eventually moved up out of the water. Once out of the water, 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 slipway iron deposits are located.
