1.	How would you explain the fact that the first ionization enthalpy of sodium is lower than that of magnesium but its second ionization enthalpy is higher than that of magnesium?
Answer» Mg has stable electronic configuration 1s² 2s² 2p⁶ 3s² due to the presence of completely filled 3s orbital from which it is difficult to remove electron than 3s¹ orbitals electron from Na (1s² 2s² 2p⁶ 3s¹). Second ionization enthalpy of Na is higher than Mg because it has stable electronic configuration of Na⁺ (1s² 2s² 2p⁶) as compared to Mg⁺ (1s² 2s² 2p⁶ 3s¹).
