d and f block elements, Chemistry

Assignment Help:
I read that in the first transition series,the stability of +2 oxidation state decreases from Sc to Cu.but,I observed that as we move along the 3d -series,the stability increases in Mn,Fe,Co,Ni,Cu,Zn for +2 oxidation state.l am in dilemma.please explain.
