Noble gases are a special group because it is the most stable group in the periodic table. Noble gases have electron valence configuration s2p6, except helium with electron valence configuration s2. This structure cause noble gases are unreactive. Although noble gases are stable and unreactive but, it could form compounds with some mechanisms. Beside that, noble gases are useful in human life. In this essay will explain briefly the properties of noble gases, their uses, as well as some compound of noble gases and their ways of preparation.
In periodic table, group of VIIIA also called noble gases group. In one period, the noble gas has smallest atomic radii. The elements of the noble gas group are not very reactive because they are stable (have eight electrons in the valence shell). The noble gases are, in fact, comparatively unreactive, but some (especially xenon and krypton) are not “inert” even though that label was once applied to the noble gas. Elements belonging to noble gases are He, Ne, Ar, Kr, Xe, and Rn (James E. House, 2008). Some properties of noble gases can be seen in the following table.
Elements belonging to noble gases are He, Ne, Ar, Kr, Xe, and Rn. First is helium (He), this element was named helium the Greek word helios, its mean “sun”. (James E. House, 2008). In 1968 Pierre Jansen found evidence of He during the total solar eclipse when he detected a new line in the solar spectrum. In 1895, Ramsay discovered He in the uranium mineral cleveite. At the same time, the Swedish chemists Cleve and Langlet discovered He in cleveite. In 1907 Rutherford and Royds demonstrated that alpha particles are He nuclei (Yulianto Mohsin, 2005). It has long been related to nuclear chemistry because of the formation of alpha particles ( 4He2+) during the decay of heavy nuclei.
