Dhamnekar Win,odd Posted November 17, 2021 Share Posted November 17, 2021 (edited) An x-ray photoelectron spectroscopy experiment with an unidentified element, X, displays an emission spectrum with four distinct kinetic energies: [math] 5.9 \times 10^{-17} J, 2.53 \times 10^{-18} J,[/math] [math]2.59 \times 10^{-20} J, 2.67 \times 10^{-20} J [/math] (Assume the incident light has sufficient energy to eject any electron in the atom.) (a)Name all of the possible ground state atoms that could yield this spectrum. (b)Calculate the binding energy of an electron in the 2p orbital of element X if the x-rays used for the spectroscopy experiment had an energy of [math] 2.68 \times 10^{-16} J[/math] (c)Consider both the filled and unfilled orbitals of element X. Determine the number of: (1) total nodes in a 4d orbital (2)angular nodes in the [math]2p_y[/math] orbital (3)degenerate 5p orbitals How to answer all these questions?

swansont Posted November 18, 2021 Share Posted November 18, 2021 I work better in electron-Volts, so 5.9e-17J = 368.25 eV (x-ray) 2.53e-18J = 15.8 eV (ultraviolet) 2.59e-20J = 0.161 eV (infrared) 2.67e-20J = 0.167eV Note that these are 3 quite different energy scales (spectroscopically speaking). What transitions would be involved in emitting a photon that has several hundred eV, around 15 eV, and around 0.1 eV? You're asked for what atoms could give you this spectrum, so you musty have access to spectroscopy data to do the comparisons Link to comment Share on other sites More sharing options...
