how do you draw the energy level diagram for aluminum?

4 Answers

  • I assume you are talking about an electronic energy level diagram. It depends on whether you are talking about a neutral aluminum atom, a molecule, the solid, etc. For a neutral atom, the electronic configuration is 1s2,2s2,2p6,3s2,3p1.

    The diagram would look like this:

    3p __ __ __

    3s __

    2p __ __ __

    2s __

    1s __

    You fill in two electrons in each blank, from the bottom to the top (1s through 3s would be completely filled with 12 electrons, and 3p would have a single electron; remember that two electrons in the same orbital, or blank, have opposite spins, up or down)

    No web site seems to show this, but it is easy to explain how to do this. Electron structure is 2.8.3 Energy levels are all increasing. 1s2 2s2 2p6 3s2 3p1 Draw two axes at right angles. Label vertical one energy, horizontal one electron shell. Mark 1, 2, 3 along horizontal axis. Put 1s2 on a short line a little way up the energy axis, above 1 on the horizontal axis. Then higher up energy axis put 2s2 above 2 on the horizontal axis. Then little higher up energy axis put 2p6 above 2 on the horizontal axis. then 3rd level Then higher up energy axis put 3s2 above 3 on the horizontal axis. Then little higher up energy axis put 3p1 above 3 on the horizontal axis. It will look a bit like staggered steps. OK?
