  Uses of Noble Gas

Uses of Noble Gas:

(A) Helium:

1. Because of its lightness and non-inflammability helium is utilized to filling balloons for meteorological observations.

2. Since of its lightness it is utilized in inflating aeroplane tyres.

3. Helium oxygen mixture is utilized by deep-sea divers as first choice to nitrogen oxygen mixtures. It is less soluble in blood than N2. It prevents “bends” that is the pain caused by formation of nitrogen bubbles in blood veins whenever a diver comes to the surface.

4. The mixture of oxygen and helium is utilized in the treatment of asthma.

5. Liquid helium (i.e., b.pt 4.2K) is utilized as cryogenic agent for carrying out different experiments at low temperatures.

6. It is utilized to generate and sustain powerful super conducting magnets that form necessary part of modern NMR Spectrometers and Magnetic Resonance Imaging system (i.e., MRI) for clinical diagnosis.

(B) Neon:

1. Neon is utilized in discharge tubes and fluorescent bulbs for the advertisement of display reasons.

2. Mixed with helium it is utilized to protect electrical instruments from high voltages.

3. It is also utilized in beacon lights for the safety of air navigation as light possesses fog and storm-penetrating power.

4. Neon light is utilized in botanical gardens as it stimulates growth and aids the manufacture of chlorophyll.

(C) Argon:

1. Mixed with 26% nitrogen it is utilized in gas filled electric lamps.

2. It is also utilized in radio valves and tubes.

(D) Krypton and Xenon:

1. Xenon and Krypton are also utilized in filling incandescent metal filament electric bulbs.

2. They are also utilized to a small extent in discharge tubes.

(E) Radon:

1. It is utilized in radioactive research and in the radiotherapy for treatment of cancer.
