Fe is Iron. It isn't 'Ir' because they got Fe from iron's Latin name, ferum. It also can't be 'Ir' because Ir is already the symbol for another element, iridium.
Ferrum (Latin for Iron) That's why Iron's symbol on the Periodic Table Of Elements is Fe. Some people say it's original name is Ferminum, but that's just another name for Scandium. Hope this helped.
