Question:medium
Noble gas 'X' is used as a diluent for oxygen in modern diving apparatus and noble gas 'Y' is used mainly to provide an inert atmosphere in high temperature metallurgical processes. 'Y' and 'X' are respectively?
Noble gas 'X' is used as a diluent for oxygen in modern diving apparatus and noble gas 'Y' is used mainly to provide an inert atmosphere in high temperature metallurgical processes. 'Y' and 'X' are respectively?
Show Hint
Remember the major uses of the noble gases:
- Helium (He): Filling balloons and airships, cryogenics, diluent in diving gas.
- Neon (Ne): "Neon" signs and fluorescent lamps.
- Argon (Ar): Providing inert atmospheres for welding and in light bulbs.
- Krypton (Kr) & Xenon (Xe): Specialized lighting (e.g., airport runways, lasers).
- Radon (Rn): Radioactive, used in radiotherapy (historically).
