Definition

1. Noun:
   • A radioactive transuranic element: "Uuq" is the temporary systematic element name and symbol for a synthetic, highly radioactive chemical element with the atomic number 114. It is a transuranic element, meaning its atomic number is higher than that of uranium (92). The element is now officially named Flerovium (Fl).

Usage Notes

• "Uuq" was a placeholder name used in the periodic table before the element received its permanent name, Flerovium. It is formed using the IUPAC systematic element naming convention for undiscovered or unnamed elements.
• This term is primarily used in historical or specific scientific contexts discussing the element's discovery and naming process. In modern chemistry, the official name "Flerovium" is used.

Examples of Usage

• Noun:
  • The discovery of element 114 was announced in 1999, and it was temporarily designated 'Uuq'. (This sentence uses 'Uuq' to refer to the element before its official naming.)
  • In the extended periodic table, 'Uuq' occupied the position below lead. (Here, 'Uuq' is used as its systematic symbol in a scientific context.)

Advanced Usage

• Systematic Nomenclature: "Uuq" follows the IUPAC method where the numerical root of the atomic number is converted into a name. For 114: 1=un, 1=un, 4=quad, hence "ununquadium", symbol "Uuq".
  • The systematic name for element 114, ununquadium (Uuq), was used until its permanent name was ratified.

Variants and Related Words

• Flerovium (Fl): The permanent name for the element with atomic number 114, named after the Flerov Laboratory of Nuclear Reactions.
  • Flerovium is a superheavy element with the symbol Fl.
• Transuranic element: Any synthetic chemical element with an atomic number greater than 92 (uranium).
  • Plutonium is another well-known transuranic element.
• Superheavy element: An element with a very high atomic number, typically above 104.
  • The synthesis of superheavy elements like Uuq is a major achievement in nuclear physics.

Synonyms

• Ununquadium: The full systematic name corresponding to the symbol "Uuq".
• Element 114: A direct reference to its atomic number.
• Flerovium: The official, permanent name of the element.
