?
(a) Write the equation for the ionization of atomic fluorine that requires 1,681.0 kJ mol™¹.
(b) Account for the fact that the first ionization energy of atomic fluorine is greater than that of atomic
oxygen. (You must discuss both atoms in your response.)
(c) Predict whether the first ionization energy of atomic xenon is greater than, less than, or equal to the
first ionization energy of atomic fluorine. Justify your prediction.
(d) Xenon can react with oxygen and fluorine to form compounds such as XeO, and XeF,. In the boxes
provided, draw the complete Lewis electron-dot diagram for each of the molecules represented below.
(e) On the basis of the Lewis electron-dot diagrams you drew for part (d), predict the following:
(i) The geometric shape of the XeO, molecule
(ii) The hybridization of the valence orbitals of xenon in XeF,
(f) Predict whether the XeO, molecule is polar or nonpolar. Justify your prediction.
