Photoelectron spectroscopy studies of silicon atoms excited by X-rays with wavelength 9 . 89 0 × 1 0 − 1 0 m show four peaks in which the electrons have speeds 2 .0 97 × 1 0 7 m s − 1 , 2 .0 93 × 1 0 7 m s − 1 , 2 .0 14 × 1 0 7 m s − 1 , and 1 . 971 × 1 0 7 m s − 1 . (Recall that 1 J = 1 kg m 2 s − 2 .) (a) Calculate the ionization energy of the electrons in each peak. (b) Assign each peak to an orbital of the silicon atom.

(b) Assign each peak to an orbital of the silicon atom.
Construct a molecular orbital diagram for carbon monoxide. Identify the relevant point group,include all of the appropriate symmetry labels and pictures, and fill in the electrons. Make sure toaccount for the difference in electronegativity between C and O. Hint: CO is substantiallyisoelectronic to N2. (PLEASE DRAW THE ENTIRE MO DIAGRAM!!!)
