WebEncyclopædia Britannica, Inc. The chemical element iron is the fourth most common element in Earth’s crust and the second most abundant metal. Iron was used by early peoples. Its chemical symbol, Fe, is taken from the Latin ferrum. The name iron is from the Anglo-Saxon iren or isern. About 5 percent of Earth’s crust is composed of iron. Web2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (e.g., S 2–)) or an anion complex (e.g., SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their predominant …
