Energy level diagram

  1. Sep 29, 2008 #1
    how do you draw the energy level diagrams for LiF molecule? i know how to draw an energy level digram for Li but how do you do it for a molecule?

    Then this is a homework question ... you need to read your text and ask specific questions.

    Where are all of the other 2p orbitals for Oxygen? What is the particular 2p orbital that would have the correct symmetry to overlap with the 2s orbital of Be? Where are all of the other valence electrons for Oxygen?

    The diagram is partially correct , the p electrons of O are more stable than the 2s of Be.

    You got more electrons in the MO than in the AO , with the current setup BeO has a bond order of zero.

    ok... i will delete some electrons from the MO.

    Again , the bond order is zero , this means that BeO has no bonds ... why are you putting the electrons in the antibonding orbitals?

    right... i dont think i put electrons in the antiboding orbitals for LiF
