Which sublevels are full when an atom has a noble gas configuration?

Answer 1

Hi, Taylor,

Both the s and p sublevels are full for the noble gasses.

He 1s²

Ne 2s²2p⁶

Ar 3s²3s⁶

Kr 4s²4p⁶, but Krypton also has a 3d shell that is full. I'm not sure if the question applies to the lower energy levels of d and f for Krypton and above.
