Fe

Iron is a chemical element with the symbol Fe (Latin: ferrum) and atomic number 26. Iron is a group 8 and period 4 element. Iron is a lustrous, silvery soft metal. It is one of the few ferromagnetic elements.

Iron and nickel are notable for being the final elements produced by stellar nucleosynthesis, and are therefore the heaviest elements which do not require a red giant or supernova for formation。 Iron and nickel are therefore the most abundant metals in metallic meteorites and in the dense-metal cores of planets such as Earth。 Iron and iron alloys are also the most common source of ferromagnetic materials in everyday use。
