Why do high atomic number


                             elements have low electronegativity?










                              High atomic number


                              elements also have low


                              electronegativity because


                              the outer electrons are at a


                              greater distance from the



                              positive nucleus, so they


                              are not as strongly


                              attracted to the atom. For                                                      Zn
