Iron

Iron (Fe) is a grey metal that has the atomic number 26 in the periodic table. It is a Transition metal and located in Group 8 of the periodic table. It has the symbol Fe.

Iron is an element that has been known since ancient times and has been an important part in the develop of humans. Iron artifacts have been found dating to 5000 BC and it is known that between 1300-1200BC Iron was easily smelted by humans and replaced bronze as the common metal for making weapons and armour. It was around 1000BC that molten Iron and carbon were mixed together to produce the alloy of steel. Iron’s symbol is Fe after the Latin ‘ferrum’ meaning iron. Iron is a well known magnetic compound due to its unpaired electrons. One third of the Earth’s mass is iron, believed to be in the core producing magnetic poles at North and South. Iron is widely used in construction especially the manufacturing of steel. It is widely used in the human body where it is important in oxygen transport in hemoglobin. It is located in Group 8 and it has a melting point of 1538°c and a boiling point of 2862°c being a solid metal at room temperature.

FAQ's

What is the Melting Point for Iron?

Iron has a Melting Point of 1538°F, meaning at 1538°F it will turn to a liquid.

What is the Boiling Point for Iron?

Iron has a Boiling Point of 2861°F, meaning at 2861°F it will turn to a Gas.

What is the Electronegativity of Iron?

Iron's Electronegativty is 1.83. Electronegativity is a measure of how strongly atoms attract bonding electrons to themselves.

What is the Heat of Vaporization of Iron?

Iron has a Heat of Vaporization of 349.6 kJ/mol.

Uses

Used in steel and other alloys. Essential for humans. It is the chief constituent of hemoglobin which carries oxygen in blood vessels. Its oxides are used in magnetic tapes and disks.

Sources

Obtained from iron ores. Pure metal produced in blast furnaces by layering limestone, coke and iron ore and forcing hot gasses into the bottom. This heats the coke red hot and the iron is reduced from its oxides and liquified where it flows to the bottom

Transition metal is any of various chemical elements that have valence electrons (electrons that can participate in the formation of chemical bond) in two shells instead of only one. They form group 3 (IIIb) through group 12 (IIb).
