"Inert" xenon actually forms several compounds, especially with the highly electronegative elements
oxygen and fluorine. The simple fluorides XeF2, XeF4, and XeF, are all formed by direct reaction of the
elements. As you might expect from the size of the xenon atom, the Xe-F bond is not a strong one.
Calculate the Xe-F bond energy in XeF6, given that the heat of formation is -402 kJ/mol.

Carbon has four valence electrons in the n = 2 energy level. An electron is transferred from the filled 2s orbital to an unoccupied 2p orbital. The energy gap between the n = 1 and n = 2 is large and no further electrons can, therefore, be promoted from lower energy levels to facilitate more bonds. All of the reasons given above explain the observation. Question 4: Select the structures in Figure 4 that are drawn correctly * II ...arrow_forward
