To form ionic bonds, Carbon molecules must either gain or lose 4 electrons. The electron donor becomes a cation (positively charged ion) and the electron acceptor becomes an anion (negatively charged ion). Paul Flowers (University of North Carolina - Pembroke),Klaus Theopold (University of Delaware) andRichard Langley (Stephen F. Austin State University) with contributing authors. Similarly, nonmetals that have close to 8 electrons in their valence shells tend to readily accept electrons to achieve noble gas configuration. A rough approximation of the electronegativity differences associated with covalent, polar covalent, and ionic bonds is shown in Figure 6.1.
