Usage

• This term is used exclusively in scientific contexts, particularly in chemistry and physics, to denote the specific element with 111 protons in its nucleus. It is often discussed in relation to nuclear research, the synthesis of superheavy elements, and the periodic table.

Examples

• Noun:
  • The discovery of atomic number 111 was a significant achievement in nuclear physics.
  • Scientists produced atoms of atomic number 111 by bombarding a bismuth target with nickel ions.

Advanced Usage

• "The element with atomic number 111": A common clarifying phrase used in scientific writing.
  • Research on the element with atomic number 111 helps test the limits of the periodic table.

Variants and Related Words

• Roentgenium (Rg): The official name assigned to the element with atomic number 111 by the International Union of Pure and Applied Chemistry (IUPAC).
  • Roentgenium (atomic number 111) is named after the physicist Wilhelm Röntgen.
• Transuranic element: Any chemical element with an atomic number greater than 92 (uranium). Atomic number 111 belongs to this group.
• Superheavy element: A classification often used for elements with very high atomic numbers, typically above 104, which includes atomic number 111.

Synonyms

• Roentgenium: The systematic element name.
• Element 111: A common numerical synonym.
