Pauli exclusion principle

  1. May 30, 2007 #1
    hey all, posted this before but no one managed to get it?
    question off a past paper that it cant do.../

    state pauli exclusion principle (can do that) and explain its consequence in an atom (can do that). Use it to determine the values of n, l ml and ms of 10 neon atoms placed in a box at ground state. what is the net z component of angular momentum of the electrons?

    any help much appriciated!

    i know the quantum numbers can only take certain values and that pauli says no 2 particles can have identical quantum numbers but can't really get answer.

    cheers all

    what quantum number do you know that are relevant i atomic physics, how are their values related to each other? What values can they obtain?

    Yes, of course you can state Pauli's exclusion principle... there's and argument about the symmetric or antisymmetric wave function (if the particle has integer or half-integer spin). You can find it well stated in whatever introductury book on QM.

    In an atom, as electron (say), have semi-integer spin, the exclusion principle forbids that all electron occupy the ground state...

    Good luck...
