Definition

1. Noun:
   • A chemical element: "atomic number 73" is the scientific designation for the metallic element with 73 protons in its atomic nucleus. This element is known for its high density, resistance to corrosion, and high melting point.
   • A specific material: It refers to the substance itself, a hard, grey, lustrous metal found in certain minerals.

Usage

• The term "atomic number 73" is used primarily in scientific, technical, and educational contexts to specify the element unambiguously by its fundamental property (the number of protons).
• In most general contexts, the element's common name is used instead.

Examples

• Scientific Context:
  • The periodic table lists the element with atomic number 73 between hafnium and tungsten.
  • Analysis confirmed the presence of atomic number 73 in the mineral sample.
• Definitional Context:
  • Tantalum is the element corresponding to atomic number 73.

Advanced Usage

• In Materials Science: The properties of atomic number 73, such as its biocompatibility and corrosion resistance, make it valuable for medical implants and chemical equipment.
• In Geology & Mining: Prospectors search for ore bodies containing minerals rich in atomic number 73.

Variants and Related Words

• Tantalum (Ta): The common name for the element with atomic number 73.
  • Tantalum capacitors are essential components in modern electronics.
• Tantalite: A principal mineral ore from which atomic number 73 (tantalum) is extracted.
  • The mine was a major source of tantalite.

Synonyms

• Tantalum: The direct synonym and common name for the element designated by atomic number 73.

Related Terms (Scientific Context)

• Transition Metal: Atomic number 73 is classified as a transition metal.
• Refractory Metal: It is part of a group of metals known for extremely high resistance to heat and wear.
