Iron, symbolized as Fe, is a chemical element and a
metal with atomic number 26. It's a transition metal known for its strength,
malleability, and magnetic properties. It's the most widely
used metal and is a crucial component of steel.
Its melting point is 1536
°C.And its density is 7.8
g.cm-3 at 20°C.
Iron is the most abundant metal on Earth and is
believed to be the tenth most abundant element in the universe. Iron is also
the most abundant element making up the Earth; the concentration of iron in the
various layers of the Earth ranges from high at the inner core to about 5% in
the outer crust, it is possible the Earth’s inner core consists of a single
iron crystal although it is more likely to be a mixture of iron and nickel; a
large amount of iron in the Earth is thought to contribute to its magnetic field.
Iron is a metal extracted to its magnetic field. Iron is a metal extracted from
iron ore and is hardly ever found in the free state.
