The third ionization energy of manganese is greater than that of both chromium and iron. This is best explained by noting that M n 2 + has blank unpaired and blank set(s) of paired electrons in its 3d orbitals, while C r 2 + has blank unpaired and blank set(s) of paired electrons in its 3d orbitals and F e 2 + has blank unpaired and blank set(s) of paired electrons in its 3d orbitals. Therefore, the larger Z value of M n explains why it has a larger third ionization energy than blank, while electron repulsion explains why it has a larger third ionization energy than blank.
