How would you account for the following ? The third ionization enthalpy of manganese (Z = 25) is exceptionally high.

Why is the third ionization enthalpy of manganese (At. no.=25) unexpectedly high ?

Account for the fact that the third ionization enthalpies of both Mn and Zn are higher than those of next element
