SUMMARY
The first ionization energy of sodium (Na) is significantly lower than its second ionization energy due to the removal of electrons from different energy levels. The first ionization involves removing one electron from the outermost shell, while the second ionization requires removing an electron from a more stable, fully filled inner shell. This transition results in a greater effective nuclear charge experienced by the remaining electrons, leading to a higher energy requirement for the second ionization.
