The second electron affinity values for both oxygen and sulfur are unfavorable (endothermic). Explain.
Notes Week 24-28 Friday, October 21, 2016 7:26 PM 11.3 Continued: • Dispersion Force (London force): intermolecularforce present in all moleculesand atoms ○ Result of fluctuations in the electrondistribution within moleculesor atoms. ○ Electrons in an atom or molecule may at any instant be unequally distributed ○ The magnitude of the dispersion force depends on how easily the electrons in the atom or moleculecan move or polarize in response to an instantaneousdipole. Larger electron cloud results in larger dispersion force If all other factors are constant, dispersion force increaseswith molar mass Shape of molecule can also have impact on dispersion force □ Longer molecu
