xenon hexafluoride
C2 (Very Low Frequency)Technical/Scientific
Definition
Meaning
A chemical compound with the formula XeF₆, consisting of one xenon atom bonded to six fluorine atoms.
A powerful fluorinating agent and one of the three known binary fluorides of xenon, notable for its reactivity and use in specialized chemical synthesis and research.
Linguistics
Semantic Notes
The term is exclusively used in chemistry. It refers to a specific, discrete chemical entity. The 'hexa-' prefix denotes the six fluorine atoms.

Learning
Memory Aids
Mnemonic
Think: 'Xenon' (the noble gas) with 'hexa' (six) 'fluoride' (fluorine atoms) attached. Visualise Xe in the centre with 6 F atoms around it.
Conceptual Metaphor
A chemical compound is a molecular machine (with xenon as the central hub and fluorines as the reactive arms).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation yields 'гексафторид ксенона', which is correct. Ensure the element name 'xenon' is not confused with similar-sounding words.
Common Mistakes
- Misspelling 'hexafluoride' as 'hexaflouride'. Incorrectly stating the formula (e.g., XeF₄ instead of XeF₆). Using it as a common noun without the article 'xenon' (e.g., 'a hexafluoride').

FAQ
Frequently Asked Questions
Yes, it is a highly reactive and corrosive compound that reacts violently with water and many organic materials, requiring specialised handling.
Primarily as a powerful fluorinating agent in research chemistry to introduce fluorine atoms into other molecules, and in the synthesis of other xenon compounds.
At room temperature, it is a colourless solid that sublimes easily, forming a vapour.
It helped debunk the old belief that noble gases were completely inert, proving they can form stable compounds under the right conditions.
