Question

justify the iron metal

Answer 1

necessary trace element for all known forms of life.

In addition, given its high abundance, low cost, and high strength, iron is the most widely used of all metals and constitutes about 95 percent of the tonnage of all metals produced worldwide. Its alloys, particularly steels, are used to make large, strong structures such as buildings, automobiles, and the hulls of ships. Iron is also used for making magnets, and iron(III) oxide in particular is used for the manufacture of magnetic storage media for computers. Iron and its alloys, however, tend to rust and need to be protected by such methods as painting, galvanization, or the application
