We highlight the classical and more exotic noble gas compounds and discuss the nature of their bonding starting with strongly bound systems and progressing to weak interactions. Noblegas chemistry was started in 1962 with the discovery of xenon hexafluoroplatinate followed with a number of compounds binding xenon or krypton. In chemistry, the noble gases are a set of chemical elements that share similar characteristics and properties. The noble gases make up about 1% of the earths atmosphere in which their major component is argon. They are completely different noble gases are colorless, monoatomic gases. Inert gases consist of six elements, namely helium, neon, argon, kripton, xenon and radon. The printable worksheetinteractive quiz combo will help assess your understanding of noble gases, which are inert gases located in group 18 of the periodic table of elements.
Noble gases are chemically inert and variably soluble in crustal fluids. Helium is much less dense than air lighter and used in filling weather balloons, airships and decorative balloons. Compare and contrast halogens and noble gases answers. Due to unreactive nature, low density and nonflammability of noble gases, they have a variety of uses listed below. All the noble gases are present in earths atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional. They are primarily introduced into hydrocarbon reservoirs through exchange with formation waters, and can be used to assess.
