Solution
- Elements present in Group 18 or Zero Group of the periodic table are termed as noble gases or inert gases.
- It includes Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Ra).
- All the elements of Group 18 have eight electrons in their outermost or valence shell, except Helium (He) which has only two valence electrons.
- Thus, noble gases have a completely filled outermost or valence shell (octet), and therefore, their electronic configuration is highly stable.
- Due to the absence of free electrons in their outermost shell, these elements have zero tendency to accept or lose any electron.
- As a result, no ionic or covalent bonds are formed and they don't participate in any chemical reactions.
