Zorluk: OrtaNoble Gases: Isolation, Electronic Structure, and Uses

Match each noble gas listed on the left with its correct industrial application or property on the right.

  • Helium (HeHe)Used to dilute oxygen in deep-sea diving gas cylinders to prevent decompression sickness
  • Neon (NeNe)Emits a characteristic bright orange-red glow in low-pressure discharge lamps for advertising
  • Argon (ArAr)Provides an inert gas shield during electric arc welding to prevent oxidation of hot metals
  • Radon (RnRn)Used as a radioactive source in cancer radiotherapy applications

Cevap

Helium pairs with deep-sea diving gas mixtures; Neon pairs with orange-red discharge advertising lamps; Argon pairs with inert shield in arc welding; Radon pairs with cancer radiotherapy.
Each noble gas has specific industrial applications: Helium is utilized in deep-sea diving mixtures due to low blood solubility; Neon is used in glowing discharge signs; Argon serves as an inert protective atmosphere in high-temperature welding; Radon is radioactive and used in cancer radiotherapy.

Adım Adım Çözüm

1
Analyze the unique physical and chemical properties of each noble gas listed.
Helium is non-flammable with low blood solubility; Neon exhibits characteristic light emission under electrical discharge; Argon is chemically inert and relatively cheap; Radon is radioactive.
Matching each noble gas to its primary industrial use depends on these distinct physical and chemical properties.
2
Correlate each gas to its specific practical application.
Helium matches diving gas mixture dilution (Heliox); Neon matches advertising discharge signs; Argon matches metal arc welding inert environment; Radon matches cancer treatment radiotherapy.
This establishes the precise pairs based on standard JAMB Chemistry syllabus requirements for noble gases.
