uuh

A scientist carefully handles a sample of uuh in a secure laboratory.

Definition
  1. Noun:
    • A radioactive transuranic element: "Uuh" is the temporary systematic element name for a superheavy, synthetic chemical element with atomic number 116. It is also known by its permanent name, livermorium (Lv).
Usage Notes
  • "Uuh" is a placeholder name used in scientific literature before an element receives its permanent name. It is formed using the IUPAC nomenclature for undiscovered or unnamed elements, where "uuh" stands for "ununhexium" (from Latin for one, for one, and for six, indicating one-one-six, or 116).
  • In modern contexts, the permanent name "livermorium" is strongly preferred. The use of "uuh" is now largely historical or in specific discussions about the element's discovery and naming process.
Examples of Usage
  • Noun:
    • The element with atomic number 116 was originally designated 'uuh'. (This sentence uses "uuh" to refer to the element's temporary name.)
    • Scientists synthesized atoms of uuh in a particle accelerator. (Here, "uuh" is used as the name for the element itself in the context of its discovery.)
Advanced Usage
  • In systematic nomenclature: The prefix "ununhexium" (from which "uuh" is derived) follows a specific pattern for element names based on their atomic number digits.
  • Historical/Discovery context: The term appears in research papers and discussions from the period between the element's discovery and the official ratification of the name "livermorium" by IUPAC in 2016.
Variants and Related Words
  • Livermorium (Lv): The permanent name for the element with atomic number 116.
    • Livermorium is a post-actinide element in the periodic table.
  • Ununhexium: The full systematic name corresponding to the symbol "uuh".
  • Transuranic element: A category of elements with atomic numbers greater than uranium (92), to which uuh/livermorium belongs.
    • Plutonium and livermorium are both transuranic elements.
Synonyms
  • Livermorium: The official synonym and permanent name.
  • Element 116: A descriptive synonym based on atomic number.
  • Ununhexium: The systematic name synonym.
