Definition

1. Noun:
   • A chemical element: "atomic number 24" is the scientific term for the chemical element with 24 protons in its atomic nucleus. It is a transition metal.
   • A specific metallic element: It refers precisely to a hard, brittle, multivalent metallic element known for its resistance to corrosion and tarnishing.

Usage

• The term "atomic number 24" is used primarily in scientific, technical, and educational contexts to specify the element unambiguously by its fundamental property (proton count).
• Example: "The isotope of atomic number 24 used in the experiment was chromium-50."

Examples

• Noun:
  • In the periodic table, atomic number 24 is positioned between vanadium and manganese.
  • The alloy's durability comes from the inclusion of atomic number 24.

Advanced Usage

• The term is used to avoid ambiguity in discussions where the element's common name might be confused with other terms or in formal scientific writing.
• Example: "Spectroscopic analysis confirmed the presence of atomic number 24 in the stellar dust."

Variants and Related Words

• Chromium (Cr): This is the common name for the element with atomic number 24. All descriptions of "atomic number 24" (hard, brittle, corrosion-resistant) apply to chromium.
  • Chromium is used to plate other metals to prevent rust.

Synonyms

• Chromium (Cr): The standard name for the element.
• Element 24: An alternative systematic name.

Related Phrases / Context

• Transition metal: The category of elements to which atomic number 24 belongs.
• Corrosion-resistant: A key property of this element.
• Alloying agent: A common use for this element, as in stainless steel.
