Iron Element Symbol Fe

Iron Element Symbol is Fe, capital F followed by lowercase e. The sequence U+0046 U+0065 identifies iron in chemical formulas, periodic tables, materials-science documents, metallurgy, and laboratory labels. Case is part of the notation: FE and fe are not the standard element symbol. Typical forms include “Fe,” “Fe(s),” “Fe₂O₃,” and “FeCl₃.” The bare symbol identifies the element, while subscripts, state labels, and neighboring element symbols define compounds or physical form. Fe²⁺ and Fe³⁺ are ionic forms and should not be substituted when the neutral element notation is intended. Preserve both letters and place any charge or subscript in the correct location. Do not interpret Fe as the word “fee,” a finance abbreviation, or an all-capital initialism. In a technical table, add the full name iron when the audience may not know the element symbol. Copying should retain U+0046 followed by U+0065. An accessible reading can say “iron” rather than spelling the letters without context. Check that automatic capitalization tools do not convert the symbol to FE. Web pages may use literal Fe or the references F e and F e. Recopy the sample “Atomic number 26: Fe,” confirm the final text still contains U+0046 U+0065, and check that the visible heading names Iron Element. This final check protects Iron Element Symbol from font substitution, accidental character loss, and intent drift.
