(i) IE1 of sodium is reduced than that of magnesium While IE2 of sodium is higher than that of magnesium.
Remedy: (i) The powerful nuclear demand of magnesium is increased than that of sodium. For these explanations, the Vitality necessary to eliminate an electron from magnesium is much more than the Strength needed in sodium. That's why, the primary ionization enthalpy of sodium is reduce than that of magnesium.
