Be sure to answer all parts. The American chemist Robert S. Mulliken suggested a different definition for the electronegativity (EN) of an element, given by IE, kJ/mol kJ/mol EA Element IE, + EA EN = 1314 141 2 F 1680 328 where IE, is the first ionization energy and EA is the electron affinity of CI 1256 349 the element. Calculate the electronegativities of O, F, and Cl using the preceding equation and the data in the table. EN(O) = kJ/mol EN(F) = kJ/mol EN(CI) = kJ/mol Determine the electronegativities of these elements on the Mulliken and Pauling scales. (To convert to the Pauling scale, divide each EN value by 230 kJ/mol.) Mulliken EN(F) Mulliken EN(CI) Mulliken EN(0) Pauling scale = Pauling scale = Pauling scale = (Pauling EN(CI) = 3.0) %3D (Pauling EN(O) = 3.5) (Pauling EN(F) = 4.0)
