Answer:
Well now compare IE for 2nd electron, Na will not give electron because it get noble gas configuration but Mg gives easily because after giving electron its octet will complete. Hence 2nd IE value of Na is higher then Mg.

Answer:
Na
Explanation:
the second ionisation enthalpy on Na is higher
after the first ionisation Na+ will occupy the configuration of 1s² 2s² 2p⁶
so during the second ionisation it has to loose electron from a completely filled shell.
the energy needed to remove electron from fully filled shell is higher
there second ionisation enthalpy of Na is higher than Mg
