Hund´s rules

  1. Sep 26, 2004 #1
    I have some problems with the following question:

    Deduce what terms may arise from the ground state configurations of the atoms of elements of Period 2 and suggest the order of their energies using
    Hund´s rules.

    Deduce what terms may arise...
    Do they mean to which terms the atoms can be excited from the ground state?

    How do I find these terms? Arent there infinitly many?

    Hund's rules will only tell you what the ground state is...

    Of course the number of terms is infinite, but the question is about for example oxygen with all its electrons in shells with n=1 or n=2. Or even more restricted, with four electrons in the 2p-orbitals.
