In which group of elements do most atoms have completely filled s and p valence sublevels?

Noble or inert gases belong to the group 8A and have completely filled stable, outermost shells. The outermost electronic configuration of the noble gases can be represented as,

1. Helium -

2. Neon -

3. Argon -

4. Krypton -

5. Xenon -

6. Radon -

So, the correct answer will be noble gases.
