Although polonium is observed to have a higher ionization energy than bismuth, it is observed to have a lower ionization energy than tellurium. Explain.

Polonium has a higher ionization energy than bismuth because it has a more effective nuclear charge. On the other hand, polonium has a lower ionization energy than tellurium due to a weaker shielding effect.
