Unformatted text preview: ent bond". Electronegativity values allow you to estimate the amount of partial ionic character (i.e. the "polarity") of a covalent bond. The table below gives electronegativity values for the chemical elements ordinarily found in biomolecules. (Cesium and Fluorine are the elements with the lowest and highest electronegativity values and are also given for orientation.) See also text Table 2.3. You will not be responsible for the numerical values, but you must know the relative electronegativities of the most important chemical elements. Ionic bonds, polar covalent bonds and non-polar covalent bonds represent a spectrum of electronegativity differences. Differences >...
