Definition

1. Noun:
   • A chemical element: "zn" is the chemical symbol for the metallic element zinc. It represents a bluish-white, lustrous metal that is brittle at room temperature but becomes malleable when heated.
   • The substance zinc: The symbol "zn" refers to the material itself, which is used in various alloys, for galvanizing iron, and occurs naturally in minerals like zinc blende.

Usage Examples

• Noun:
  • The alloy is composed of copper and zn. (The alloy is composed of copper and zinc.)
  • Galvanized steel is coated with a layer of zn to prevent rust. (Galvanized steel is coated with a layer of zinc to prevent rust.)

Advanced Usage

• In chemical formulas: Used to denote zinc atoms in the composition of compounds.
  • The mineral sphalerite has the formula ZnS. (The mineral sphalerite has the formula ZnS.)
• In technical specifications: Used in industrial and scientific contexts to specify materials.
  • The battery anode is made of high-purity zn. (The battery anode is made of high-purity zinc.)

Variants and Related Words

• Zinc (n): The full name of the element represented by the symbol "zn".
  • Zinc is an essential trace element for human health.
• Zinc blende (n): A natural mineral form of zinc sulfide (ZnS), also called sphalerite.
• Galvanize (v): To coat iron or steel with a protective layer of zinc.
  • They galvanize the steel beams to protect them from corrosion.

Synonyms

• Spelter: A commercial name for impure zinc, especially in the context of slabs or ingots.
