The road to electronegativity is full of twists and turns, of hidden bright and dark places which surprise every step and stop of the way. The first stop would be the chemical element of metallic palladium. Electronegativity is the tendency of nuclei to attract electrons. Not exclusively electrons, since the nuclei by conventional agreement, are always electrically positively charged they are known to attract anything that has a net negative electric charge like electrons, muons, and tau particles. The latter are heavier versions of the electrons. Electron, muon, and tau all have the same unit of electric charge that is -1 unit of the basic electronic charge of 16.0217653 ¸10 coulombs and intrinsic spin of ½ while their mass values and magnetic moments are different.
The metal palladium has a value for electronegativity of 2.2 in the Pauling scale. See http://en.wikipedia.org/wiki/Electronegativity. As noted in the chart, fluorine is the most electronegative of all the elements while palladium in just somewhere in the middle. However, there are approximately 6 elements with the same value of 2.2 which include the element of hydrogen, the key ingredient for fusion. To be continued.
