    Pauling's Electronegativity scale is a measure of the difference in electronegativity between atoms bonded together in a molecule. Pauling's electronegativity scale is uses the differences in electronegativity between atoms in a bond to determine how electrons are being shared between atoms in a molecule. Remember, electronegativity basically describes how well atoms in a bond are sharing electrons. Ionic bonds means that one atom has actually take the "shared" electron to itself. An example is NaCl. Basically, Na gives Cl an electron and really there is no sharing between the atoms. Here the electronegativity is very high and there is little or no covalent bonding between the ...

    Solution Summary

    This solution explains how to estimate the percentage nature of different compounds using Pauling's Electronegativity Scale and applies this by estimating the percent covalent nature of a series of compounds.
