Definition

1. Noun:
   • A hard grey lustrous metallic element that is highly resistant to corrosion; occurs in niobite and fergusonite and tantalite: "Ta" is the chemical symbol for the element Tantalum.

Usage

• Noun:
  • The word "ta" is almost exclusively used in scientific, technical, and industrial contexts to refer to the element Tantalum. It is not used in everyday conversation.

Examples

• Noun:
  • Tantalum (Ta) capacitors are known for their high stability and reliability.
  • The mineral sample was analyzed and found to contain traces of Ta.

Advanced Usage

• "Ta" as a symbol: In chemistry and materials science, "Ta" is used in formulas, equations, and technical specifications.
  • The alloy's composition is listed as 60% Niobium (Nb) and 40% Tantalum (Ta).

Variants and Related Words

• Tantalum (n): The full name of the element for which "Ta" is the symbol.
  • Tantalum is used in the production of electronic components.
• Tantalite (n): A mineral that is a primary ore of tantalum.
  • The mine produces tantalite, from which tantalum is extracted.

Synonyms

• Tantalum: This is not a synonym but the full name of the element represented by the symbol "Ta".

Notes on Different Meanings

• The entry "ta" as a chemical symbol for Tantalum is distinct from the informal British English interjection "ta" meaning "thank you." They are homographs (same spelling) but completely different words with different origins and uses. This entry focuses solely on the element.
