Where Would You Locate The Element With Electronic Configuration 2, 8 In The Modern Periodic Table?
Note: Group 18 elements are known as noble gases or inert gases. They are helium, neon, argon, krypton, etc. All the noble gases have 8 electrons in their outermost shell (except helium which has only 2 electrons) in the K valence shell. Thus, the valence shells of all the noble gases are completely filled with electrons.
