The upper steadiness from the wholly loaded noble gasoline configuration contributes to really higher next ionisation enthalpy for sodium. On the other hand, Ma+ fashioned immediately after shedding first electron still has another electron in its outermost (3s) orbital. Because of this, the second ionisation enthalpy of magnesium is much lesser than that of sodium.
