Definition

Noun 1. The chemical element Iron: A heavy, ductile, magnetic metallic element with the symbol Fe and atomic number 26. In its pure form, it is silver-white but readily oxidizes (rusts). It is a crucial material used widely in construction, tools, and machinery, and it plays an essential biological role, particularly in the transport of oxygen in the blood.

Usage Examples
  • Noun:
    • The chemical symbol for iron is Fe.
    • Hemoglobin contains Fe, which binds to oxygen molecules.

Advanced Usage
  • In scientific and technical contexts, Fe is the standard symbol used in chemistry, metallurgy, and biology to denote the element iron, avoiding the ambiguity of the common word.
    • The mineral's composition was listed as SiO₂ and Fe₂O₃.
Variants and Related Words
  • Iron (n): The common English name for the element Fe.
  • Ferrous (adj): Relating to or containing iron, especially with a valence of +2.
    • Ferrous metals are magnetic.
  • Ferric (adj): Relating to or containing iron, especially with a valence of +3.
    • Ferric oxide is another name for rust.
Synonyms
  • Iron (the common term, not the symbol)
Notes
  • Fe is not typically used in everyday conversation. It is a specialized term (a chemical symbol) used in academic, scientific, industrial, and medical writing. In most general contexts, the word "iron" is used instead.
