A scientist carefully handles a sample of ununquadium in a secure laboratory.
Definition
Noun: A synthetic, radioactive chemical element with the symbol Uuq and atomic number 114. It is a transuranium element, meaning it is heavier than uranium, and is classified as a post-transition metal. It was temporarily named ununquadium (from Latin un for one and quad for four, indicating "one-one-four") before being officially named flerovium (Fl) in 2012.
Usage Examples
- Scientists synthesized ununquadium in a particle accelerator by bombarding plutonium with calcium ions.
- The discovery of ununquadium was officially recognized in 2011.
- Due to its radioactivity, ununquadium exists only for a very short time in laboratory conditions.
Advanced Usage
- In nuclear chemistry: The term is used to discuss the synthesis and properties of superheavy elements in the periodic table.
- Research on ununquadium helps test the "island of stability" theory for superheavy nuclei.
Variants and Related Words
- Flerovium (Fl): The permanent name for element 114, honoring the Flerov Laboratory of Nuclear Reactions.
- Element 114: A neutral numerical designation.
- Eka-lead: A historical name used in Mendeleev's predictions, indicating it would sit below lead in the periodic table.
Synonyms
- Flerovium (current official name)
- Element 114
Notes on Meaning
- The word ununquadium is now primarily of historical and pedagogical interest, as the element has been officially renamed. It is used in contexts discussing the history of element discovery or in older scientific literature.
