Iron

Located in Group 8 and Period 4 of the Periodic Table is the most common element in the earth. This is Iron.

Iron's discovery is currently unknown ,because the discovery date was before 5000 BC. But, in Mesopotamia (Iraq) there is evidence people were smelting iron around 5000 BC. Artifacts made of smelted iron have been found dating from about 3000 BC in Egypt and Mesopotamia.

    

The first picture when ancient people were smelting iron in 5000 BC

       Iron got its name from the Anglo-Saxon word "iron' or "iren" ,and the origin of the symbol "Fe" comes from the Latin word "ferrum"meaning "iron" .

       Possibility the word iron is derived from earlier words meaning "holy metal" because it was used to make the swords used in the Crusades .

How Iron got its name?

Iron got its name from the Anglo-Saxon word 'iron' or 'iren' , and the origin of the symbol "Fe" comes from the Latin word 'ferrum', meaning iron.
