31. I feel that unlike a redox potential, electronegativity isn't a strictly transitive property. 32. K Boiling Point : ? 350?0 K Specific mass : ? 13.65 Electronegativity :? 33. Because of the higher electronegativity of lithium, some of its compounds have a more covalent character. 34. Thus, it is this semi-empirical formula for bond energy that underlies Pauling electronegativity concept. 35. The carbonyl group is polar because the electronegativity of the oxygen is greater than that for carbon. 36. The left side ( from ionic to metallic ) is for delocalized bonds with varying electronegativity difference. 37. Because of the high electronegativity of halogen atoms, NCI is a common choice for their analysis. 38. With the same number of oxygens around E, acid strength increases with the electronegativity of X. 39. It was found that increased electronegativity of the ligands on the palladium nanoparticles increased their catalytic activity. 40. The numbers beside the compounds show the electronegativity difference between the elements based on the Pauling scale.
