SUMMARY
The highest second ionization energy among the elements Na, Mg, Al is found in Magnesium (Mg), due to its stable electron configuration after the removal of one electron. In the set Na, K, Fe, Iron (Fe) exhibits the highest second ionization energy, attributed to its greater nuclear charge and electron shielding effects. Lastly, in the group Li, Be, Mg, Beryllium (Be) has the highest second ionization energy, as it has a full outer shell after losing one electron, making it energetically unfavorable to remove a second electron.
