Definition

1. Noun:
   • A silver-white metallic element of the platinum group: "Atomic number 46" is the scientific designation for the chemical element palladium (Pd). It is a rare, lustrous metal that is similar to platinum in appearance and properties.
   • A non-tarnishing metal used in alloys: This element does not react easily with air at normal temperatures, maintaining its shine. It is often alloyed with gold for use in jewelry and has significant industrial applications, particularly as a catalyst.

Usage Examples

• Noun:
  • The catalyst converter contains a small amount of atomic number 46.
  • Jewelers sometimes use atomic number 46 to create white gold alloys.

Advanced Usage

• In scientific nomenclature: The term "atomic number 46" is used primarily in systematic scientific contexts to unambiguously identify the element, especially in databases, periodic tables, and technical literature.
  • The sample was found to contain traces of atomic number 46.

Variants and Related Words

• Palladium (Pd): The common name for the element with atomic number 46.
  • Palladium is a key component in automotive catalytic converters.
