The change in the third ionization energy does not vary smoothly across the first transition series. Why? Please select all that apply.

Question

Quizplus · Accepted Answer

The change in the third ionization energy is not smooth across the first transition series because of the loss of paired electrons when iron is oxidized from 2+ to 3+ and the loss of an unpaired electron when manganese is oxidized from 2+ to 3+. These changes result in a significant increase in ionization energy compared to the other transition metals in the series.
