How close are the Mulliken and Pauling electronegativity scales?

(a) Use Eq. 2 in Topic 2D to calculate the Mulliken electronegativities of C, N, O, and F. Use the values in kilojoules per mole from Figs. 1F.8 and 1F.12 and divide each value by 230 kJ · mol^-1 for this comparison. The Pauling values are those in Fig. 2D.2.

(b) Plot both sets of electronegativities against atomic number on the same graph.

(c) Which scale depends more consistently on position in the periodic table?
