I presume you're talking about ferrous and ferric. It's been a few years but I think its ferrous for the lower valency. (Now that you know the terms you should be able to find out)
Hope I'm helping you. Its obvious you're doing chem hw...I think I helped you with valence shells too :-p

ferrous +2 (lower valency)

The trick to remembering valance is "ic-up" so ferric is higher than ferrous and stannic (tin) is higher than stannous and so on.
