Photoelectron spectroscopy studies of silicon atoms excited by X-rays with wavelength 9.890 × 10-1º m show four peaks in which the electrons have speeds 2.097 × 107 m s-!, 2.093 x 107 m s-!, 2.014 × 107 m s', and 1.971 x 107 m s-1. (Recall that 1 J = 1 kg m² s-2.) (a) Calculate the ionization energy of the electrons in each peak. (b) Assign each peak to an orbital of the silicon atom.

3h2 AE21 = (9.35E-18 J) 8mL² (3) (a) Calculate the energy using a "box" length that corresponds to the average C=C bond length of 139 pm and compare that to the experimental energy calculated using max = 162 nm (1.23E-18 J) (b) You should have discovered a large discrepancy between the values that you calculated in (a). Based on our discussions of the particle-in-a-box model, what do you think is the reason for the discrepancy. (c) Propose a technique for correcting the model to better align with experimental results.
