weightlift comes from the Latin word ferrum. From ferrum its symbol became Fe. The atomic arrive of branding entreat is 26, and its atomic weight is 55.845. crusade is a magnetic, bendable, shiny white gilded element.Pure iron has a hardness that ranges from 4 to 5. It is soft and ductile. agitate can be easily magnetized at ordinary temperatures and at 790C the magnetic property disappears. Pure iron melts at rough 1535C, boils at 2750C, and has a specific gravity of 7.86. Chemically, iron is an active metal. When loose to humid air, iron forms a reddish-brown, flaky, decay known as rust. exhort is the fourth most abundant element in the Earths crust. Because it is so common, iron has been used by human society for thousands of years.

The beginnings of modern processing of iron can be traced back to central Europe in the mid-14th nose candy BC. Pure iron has limited use in todays world. Commercial iron always contains small amounts of carbon and other impurities that vary its physical properties, which are much improved by the further do-gooder of carbon and other alloying elements. This helps to prevent oxidation, also known as rust. Iron is an essential part of a healthy diet. Iron compounds are busy for medicinal purposes in the treatment of anemia, when the amount of hemoglobin or the number of red blood corpuscles in the blood is lowered.
