(i) IE1 of sodium is decrease than that of magnesium Whilst IE2 of sodium is better than that of magnesium.
Remedy: (i) The effective nuclear cost of magnesium is better than that of sodium. For these reasons, the Electricity needed to take out an electron from magnesium is greater than the Vitality required in sodium. For this reason, the primary ionization enthalpy of sodium is decreased than that of magnesium.
