2) Stability of the fully-filled orbitals






           d block elements donate electrons from


               4s orbitals to form cations.




               Example:



                   Zn :               1s 2s 2p 3s 3p 4s 3d                                    10
                                                             6
                                                                     2
                                                                             6
                                                                                      2
                                            2
                                                    2
                                                                                        6
                                                                               2
                                                      2
                   Zn     2+            :       1s 2s 2p 3s 3p 3d                               10
                                                                       6
                                                              2
