What Is Element Fe? Properties, Uses, And Facts About Iron 🔍 TL;DR: What Is Element Fe? **Iron (Fe)** is a transition metal with the atomic number **26**, symbolized by “Fe” (from the Latin *ferrum*) It’s one of the most abundant elements on Earth, found in the Earth’s core, rocks, soil, and even in our bodies Iron is essential for life, playing a critical role in oxygen transport (via hemoglobin in blood), energy production, and DNA
Iron | Element, Chemical Formula, Chemical Name, Atomic Mass . . . Compounds of iron in the +2 state are designated ferrous and contain the pale green Fe 2+ ion or complex ions Compounds of iron in the +3 state are called ferric and contain the Fe 3+ ion (which is yellow to orange to brown, depending on the extent of hydrolysis) or complex ions
