Nobel Gases
Nobel Gases
Noble Gases: The noble gases are helium, neon, argon, krypton, xenon and radon, which are also called rare gases because of their low amount on the earth. Due to their chemical inertness, they are called inert or noble gases. All the noble gases, except radon, are present in atmosphere. Radon is produced in the radioactive decay of radium. Helium is present in sun's atmosphere. All of them are colourless and odourless gases. As liquids these gases are used for providing very low temperatures.
Argon is the most plentiful of these gases and is used as an inert atmosphere to surround aluminium, titanium and certain types of steel when they are welded. This means that the argon stops the metals from burning or forming outside coatings of oxide, which would make it difficult for them to be joined successfully. Light bulbs also contain argon to prevent the filaments from burning out.
Neon is extensively used for making advertising signs. Tubes filled with the gas glow red when a high voltage is applied across the gas.
Helium is used as an alternative to hydrogen in meteorological balloons because unlike hydrogen, does not burn. It is also used to dilute the oxygen, which deep-sea divers use because both pure oxygen and nitrogen are dangerous to breathe in at the high pressures that exist under water. Krypton and xenon are put into some electrical valves and T.V tubes, and in high-powered lamps in lighthouses and miner's lamps.
