Particle in a 2D box question

  1. Dec 3, 2011 #1
    1. The problem statement, all variables and given/known data
    use the Aufbau process to determine the ground state electronic configuration for the 2D sqare well if it contains 4 electrons. what is the multiplicity of the ground state electronic configuration? what is the energy of this 2 D 4 electrons system? and is the system diamagnetic or paramagnetic?

    2. Relevant equations

    the questions posted above are the second part of the questions, in the first part, the answer tells me that it is a 2D box with 2 degeneracy states nx=1, ny=2 or nx=2, ny=1.

    3. The attempt at a solution
    2 denerate state means multiplicity of 2? i have no idea of the other questions tho, how do you draw eletronic configuration from particle in a box model??? plus i thought particle in a box model only predicts pi bonds because they are delocalised? so should the ground state configuration exclude s orbitals and starts with p?????
