Pauli's Exculusion Principle

    I know that pauli's exclusion principle states that no 2 identical fermions can occupy the same quantum state. I understand this for let's say a He atom, but what is going on in 2nd energy level of a Neon atom? How are all the electrons in different quantum states?

    Thanks

    Write down the electron shell+subshell configuration of Neon and label each electron through its 4 quantum numbers.

    Thanks
    n=1 shell
    [tex]1s^2[/tex]

    n=2 shell
    [tex]2s^2,2p^6[/tex]

    I dont know how do do this...

    So far it's chemistry (sure derived from QM).Question:Do u know QM??

    Umm, I have the understandin of QM, If you could give me a brief explanation of the quantum numbers and the exclusion principle I would research on it and learn more about it.

    The part with the quantum numbers and their origin/signification is more complex & pretty mathematical.Do you know group theory???

    No, maybe I'm too undereducated to understand the exclusion principle, maybe you can point me in the right direction, where should I start?

    With a solid course on analytical mechanics.Quantum Mechanics quantizes classical system described by Hamilton's formulation of Classical Mechanics.
