Still a bit confused about electron orbitals?

  1. Apr 25, 2012 #1
    Hey Everyone,

    If you have an electron with the various energy levels: -14 eV, -30 eV, -52 eV, -80 eV.

    And that the electron can only move between these levels.

    How do I go about finding the photo energy that is emitted?

    Do I just subtract the various levels?
    Ex. 14 - 30 = -16 etc?

    That is right. An electron which goes from -14eV to -30eV can emit a photon with 16 eV (and will usually do so, but there are some other options, too).
