Statement I: IP3 of Mn is high, IP3 of Fe is lowStatement II: Mn+2(d5) and Fe+3(d5) are highly stable

Manganese after the loss of two electrons acquires stable configuration3d5;Thus it has high third IP;Iron after the loss of two electrons has the configuration,3d6;Iron has a great tendency to lose the third electron and acquire stability;Thus third IP of iron is very low;
