Definition

Noun: 1. A chemical element: The element with the symbol Fe and atomic number 26. It is a heavy, ductile, magnetic, metallic element that is silver-white in pure form but readily oxidizes (rusts). It is a crucial component in steel and is used extensively in construction, tools, and armament. It also plays a vital biological role, particularly in the transport of oxygen by the blood via hemoglobin.

Examples of Usage

• Noun:
  • The core of the Earth is believed to be composed largely of atomic number 26.
  • A deficiency of atomic number 26 in the diet can lead to anemia.

Advanced Usage

• Scientific Context: In chemistry and physics, "atomic number 26" is the precise, systematic identifier for the element iron, used to avoid ambiguity.
  • The isotope Fe-56, which has atomic number 26, is particularly stable.

Variants and Related Words

• Iron (Fe): The common name for the element with atomic number 26.
  • The bridge's framework is made of iron.
• Ferrous: (Adjective) Relating to or containing iron, especially with a valence of +2.
  • Ferrous metals are attracted to a magnet.
• Ferric: (Adjective) Relating to or containing iron, especially with a valence of +3.
