Which element has the chemical symbol 'Fe'?

The story behind the answer

Fe is the chemical symbol for iron, from the Latin name ferrum. That’s why tin is Sn (stannum), silver is Ag (argentum), and gold is Au (aurum), not Fe.

Iron is one of the most widely used metals, forming steel when alloyed with carbon. It’s abundant in Earth’s core and essential for life: hemoglobin uses iron to carry oxygen in blood. Iron commonly appears as ferrous (Fe2+) and ferric (Fe3+) forms—hence “ferrous metals” and reddish-brown rust (iron(III) oxide). Memory tip: Fe = Ferrum; picture a Ferris wheel made of iron, or think “FE-rry carries O2” to link Fe with oxygen-carrying hemoglobin.
