Download Solution PDFThe correct answer is Xenon.
Key Points
- Xenon is a noble gas, which is typically found as a monoatomic gas in nature.
- Xenon is chemically inert and does not readily form compounds with other elements.
- It is one of the rare gases found in the Earth's atmosphere, with a concentration of about 0.0000087% by volume.
- Being monoatomic means that Xenon exists as single atoms rather than molecules.
Additional Information
- Noble Gases
- Noble gases include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
- These gases are characterized by their lack of chemical reactivity due to having complete valence electron shells.
- Monoatomic Gases
- Monoatomic gases consist of single atoms not bonded to each other.
- Examples include noble gases like Helium, Neon, and Argon, in addition to Xenon.
- Uses of Xenon
- Xenon is used in flash lamps, arc lamps, and as a general anesthetic.
- It is also utilized in ion propulsion systems for spacecraft.
- Chemical Inertness
- The inertness of noble gases makes them ideal for use in conditions where reactions are undesirable.
- This property is due to their filled outer electron shells, which make them stable and unreactive.
