                                                                    delocalised electron
       This model of magnesium is 
       inaccurate because: 
       a) the cations should be smaller            2+         2+        2+
          than the electrons
       b) there should be one delocalised 
          electron for every cation                2+         2+        2+
       c) there should be two delocalised 
          electrons for every cation
       d) none of the above                        2+         2+        2+
