Discovery and uses of the Noble Gases (Group 0)

HideShow resource information
Argon
Discovered: 1895 by Rayleigh and Ramsey - Measured ddensity of gasses and compared nitrogen made from ammonia to nitrogen from air. Discovered there was a gas in air not yet found. Uses: Lightbulbs as unreactive. Welding to prevent oxygen interaction
1 of 5
Neon
Discovered: 1898 by Ramsey and Travers - Discovered other lines in the visible spectrum for argon. Uses: flourescent lights as glows when electricity is passed through it and in discharge tubes
2 of 5
Krypton
Discovered: Spectroscopy when known constituents were boiled off a sample of air. Uses: flourescent lights and discharge tubes
3 of 5
Xenon
Dicovered: when it glowed bright blue in a discharge tube. Uses: photographic flash lamps, stroboscopic lamps, bactericidal lamps, high-intensive arc-lamps for motion picture projection and high-pressure arc lamps to product ultraviolet light.
4 of 5
Helium
Discovered: Late 1880s by Ramsey - Recorded a visible spectrum for an unknown gas which confirmed the earlier discovery of helium. Uses: Airships and weather balloons as it is much less dense than air and non-flammable
