Electron Configuration

  1. Oct 19, 2011 #1
    1. The problem statement, all variables and given/known data
    Write the electron configuration for SiO4.


    2. Relevant equations



    3. The attempt at a solution
    My professor said we just need to show the configuration for Si and O separately.

    I think Si gains four electrons, so its configuration is 1s2 2s2 2p6 3s2 3p6

    But Oxygen I'm not sure about. Each oxygen only gains one electron, so would it be

    1s2 2s2 2p5?

    It's been a loooong time since I did chem and I can't remember how this works. Am I doing this right?

    It doesn't make sense. First of all - no such things as SiO4. Shouldn't it be SiO42-?

    Then - there is no such thing as separate configurations of atoms in a molecule. In ionic compounds you can write electron configuration of ions, but bonds in SiO42- are not ionic.

    Sorry, I have no idea what your prof is asking for.
