Periods IIIB through XIIB in the Periodic Table...

Alright, here's the set-up to my question:

The oxidation states for the elements in these groups (columns) are as follows...

IA: +1 alkali metals
IIA: +2 alkali earth metals

VA: -3
VIA: -2
VIIA: -1 halogens

Question: do those damned elements between IIIB through XIIB follow any trends within their groups?

I was missing questions on Kaplan b/c I didn't know that Cu can be Cu+ or Cu2+ and that Fe can be Fe2+ or Fe3+.

Thanks a lot for reading this.

From what I remember I dont think there is any rhyme or reason to their ions charge...at least from what they tell you in gen. chem. I think you just have to remember what the possibilities are or they have to tell you specifically in the problem. Im not 100% sure about it, so maybe someone else can chime in. Sorry I couldnt help more.
