    noble gases will always have a filled orbital remember that

    this topic is so challenging for me:/ so that means that it would have an energy level of 4? @Photon336

    [Ar] 3s^2 3d^10, is wrong b/c it's 4s^2 then 3d [Ar] 4s^2 4p^2 you can't have 4p^2 filling before 3d. similar as 1. [Ar] 4s^2 3d^10 4p^2 (noble gases have the p orbital filled. [Ar] 3s^2 3p^6 makes the most sense to me.
