Noble Gases

1. Noble Gases A peek into the lives of our less reactive friends By Josh Allred

2. What are Noble Gases?

3. All noble Gases • Belong to group 8 on the periodic table • Are naturally occurring • Have very low chemical Reactivity • At room temp are • Gases • Colorless • Odorless • Tasteless

4. Where do we get them?

5. Fractional Distillation • Regular air is compressed and cooled to liquid state • Subsequent mixture is slowly decompressed, which increases the temperature • Different elements boil at different temperatures

6. Helium • Atomic Number - 2 • Atomic Mass – 4.002602 • Boiling point - 4.4 ° K, -268.75 °C, -451.75 °F • Discovered - 1895 by Per Teodor Cleve and Nils Abraham Langlet • Primarily obtained through separation of natural gas

7. Uses for Helium Regular Awesome • To cool superconducting magnets in things like • MRI’s • Particle accelerators (CERN) • Helium-air mixture for deep sea diving • Changing your voice • As a shield gas for arc welding • Flight • Balloons

8. Neon • Atomic Number – 10 • Atomic Mass – 20.1797 • Boiling Point – 24.56 °K, -248.59 °C, -410.94 °F • Discovered – 1898 by Sir William Ramsay and Morris W. Travers • Primarily obtained through fractional distillation of air

9. Uses for Neon Regular Awesome • Old school signs • Neon Helium lasers • Cryogenic refrigerant • Old school signs • Vacuum tubes • High voltage indicators

10. Argon • Atomic Number – 18 • Atomic Mass – 39.948 • Boiling Point – 87.30 °K, -185.85°C, -308.83 °F • Discovered –1894 by Lord Rayleigh and Sir William Ramsay • Primarily obtained through fractional distillation of air

11. Uses for Argon Regular Awesome • Used in surgery to • Destroy cancer cells • Blue Argon lasers can • Weld arteries • Destroy tumors • Correct eye defects • Preserve the Declaration of Independence • Gas filling for incandescent lights • Thermal insulation • Shielding gas for welding • Food preservative • Poultry asphyxiant (which is still pretty awesome)

12. Krypton • Atomic Number – 36 • Atomic Mass – 83.798 • Boiling Point – 119.93 °K, -157.36 °C, -251.25 °F • Discovered – 1898 by Sir William Ramsay and Morris Travers • Primarily obtained through fractional distillation of air

13. Uses for Krypton Regular Awesome • Particle physics (CERN used 27 tons of liquid Kr) • MRI, CT scans • High powered lasers • Lighting • Mixed with Argon for energy efficient bulbs • Used in “neon” signs which are painted for different colors • High speed photography flashbulbs

14. Xenon • Atomic Number – 54 • Atomic Mass – 131.293 • Boiling Point – 165.03 °K, -108.12 °C, -162.62°F • Discovered – 1898 by Sir William Ramsay and Morris Travers • Primarily obtained through fractional distillation of air

15. Uses for Xenon Regular Awesome • Anesthesia ( 4x more effective than NO2) • Treating brain injuries • Ion propulsion for jets and spacecraft • Lighting • Expensive flash photography • IMAX film projection • Expensive Auto Headlights • Plasma Televisions • Lasers
