Inertness of Noble Gases
There are some elements which do not combine with other elements.These elements are : Helium,Neon, Argon, Krypton, Xenon and Radon.They are known as noble gases or inert gases because they do not react with other elements to form compounds. We know that only the outermost electrons of an atom take part in a chemical reaction. Since the noble gases are chemically unreactive,we must conclude that the electron arrangements in their atoms are very stable which do not allow the outermost electrons to take part in chemical reactions.We will now write down the electronic configurations of the noble gases to find out the exact reason for their inert nature.
