Difficulty: EasyNoble Gases: Isolation, Electronic Structure, and Uses

Match each noble gas on the left with its corresponding primary application or characteristic property on the right.

  • HeliumUsed in filling weather balloons and in breathing mixtures for deep-sea divers due to low solubility in blood
  • NeonUsed in advertising signs and glow lamps because it produces a reddish-orange light when an electric discharge passes through it
  • ArgonUsed to create an inert shield during electric arc welding and to fill incandescent light bulbs
  • RadonA radioactive gas used in radiotherapy for treating cancer

Answer

Helium matches with filling weather balloons and deep-sea diving gas mixtures; Neon matches with advertising signs producing reddish-orange glow; Argon matches with inert shielding in arc welding and light bulbs; Radon matches with radioactive cancer treatment.
Each noble gas possesses specific physical characteristics: Helium's light weight and low solubility suit balloons and diving gas; Neon's electrical discharge color suits signage; Argon's abundance and chemical inertness suit welding and lighting; Radon's radioactivity suits cancer treatment.

Step-by-Step Solution

1
Identify the key physical and chemical properties of each Group 0 (noble gas) element.
Helium is the lightest non-flammable gas with minimal blood solubility; Neon exhibits characteristic light emission; Argon is an abundant inert gas; Radon is radioactive.
Matching noble gases requires aligning their unique electronic stability and physical properties with industrial and medical uses.
2
Pair each gas to its correct industrial or medical application.
Helium pairs with weather balloons/diving gas; Neon pairs with advertising glow lamps; Argon pairs with welding/bulbs; Radon pairs with radiotherapy.
Each application specifically relies on the unique physical state or reactivity profile of that element.

Key Concept

Noble gases are unreactive Group 8/0 elements with stable octet (or duplet) electron configurations whose distinct physical properties dictate specific industrial and medical uses.
