                 1. What species have lone electron pairs?
                    _____________________________________________




                2. Based on the transfer of free electron pairs that occur in figure 17, it
                    is known that SO  is an acid. So, what is the definition of acid
                                        2
                    according to Lewis theory?

               3. Based on the electron pair transfer that occurs in figure 17, it is

                   known that CaO is a base. So, what is the definition of base
                   according to Lewis Theory?
