What element has the symbol 'Fe'?

The story behind the answer

Fe is the symbol for iron, from the Latin word ferrum—hence related terms like ferrous (Fe2+) and ferric (Fe3+). The other options have different symbols: fluorine is F, francium is Fr, and fermium is Fm.

Iron (atomic number 26) is one of Earth’s most abundant and useful metals—central to steel, essential in hemoglobin for oxygen transport, and responsible for familiar rust (iron oxide). Memory tip: think “Fe = ferrum = ferrous = iron.” If you see “Fe” in chemistry or on a blood test (serum Fe), it points to iron.
