Why inert gases are one atom ?

1 Answer

Answer :

Inert gases are very stable. The last energy level of any atom of these gases is filled by electrons. Electrons do not exchange or share with any of its other elements, not even among themselves. As a result, no bonds are formed, so inert gases are one atom.
