But a duplet configuration is exhibited by Helium.

Thus, they have a very stable electronic configuration as their octane is fully and completely filled with electrons. The members of the group 18 elements have 18 valence electrons, that is they have 8 electrons in their outermost orbitals.

The characteristics of the Noble gases are as follows:. He was awarded the Nobel Prize in Chemistry in 1904 for his achievements. Noble gas Radon was discovered by Friedrich Ernst Dorn while the remaining four noble gases Neon, Argon, Krypton and Xenon were discovered by Sir William Ramsay. Noble gas Helium was discovered by Pierre Janssen and Joseph Norman Lockyer. Group 18 elements (also called zero groups) Here we are providing a list of Inert Gases with their electronic configuration вЂ“ Energy and particles, helium nuclei (alpha particles) and radon atoms are seen to be emitted out of the nuclei of the radium atom spontaneously. The most commercial methods of obtaining the Noble gases are in the air except for helium and radon and they are extracted out of the air by the liquefaction and fractional distillation methods. Therefore, after hydrogen, helium is the second most abundant gas that is found in the earthвЂ™s atmosphere. Their structural identification along with the finding of their characteristics that shows that in the special condition they do react to form some of the special compounds have correctly put them in group 18 of the modern periodic table.ДЄs the atomic number of the noble gases increases their abundance in the atmosphere decreases. For many decades they are put into zero groups of the traditional periodic table as they are thought to be completely non-bonding to other atoms, so that the atoms of the noble gases do not react with the atoms of any other elements for a new chemical compound. They are generally colourless, odourless and tasteless and non-inflammable gas. So, elements of group 18 are also called zero group elements. These gases are also known as Noble Gases. The word inert means chemically unreactive. This is the reason these elements are known as inert gases or inert elements. Elements of group 18 are all gases and have completely filled outermost orbital, that's why these elements are highly stable and donвЂ™t react with other elements easily.
