Why does Fe stand for iron?
The Latin name for iron is ferrum, which is the source of its atomic symbol, Fe. The word iron is from an Anglo-Saxon word, iren. The word iron is possibly derived from earlier words meaning “holy metal” because it was used to make the swords used in the Crusades, according to WebElements.
