Aluminium has the highest nuclear charge, so its 2p peak should have the largest binding energy, but shielding effects reverse this trend.
Justify your answer.
Although aluminium (Al) has the highest nuclear charge among the second-period elements (Z = 13), the binding energy of its 2p electrons is not the largest. This is because the effective nuclear charge (Z_\text{eff}) experienced by an ______ ___ ______ _______ ________ ________ ___ ________ _______ ____ _________ ____.
