How do we order the following,considering their stability when they are in (+3) oxidation state?
Al
Ga
Tl
Sc
We've been taught that (+3) is the common oxidation state of Sc.
And when it comes to Al ,Ha,Tl how do we order them?

The best advice I can give is to use the activity series to order the reactivity (more reactive would mean less stable). You can Google activity series. However, many of the tables are abbreviated and will not list Ga, Tl and Sc so you may need to look at several to find a table that includes those. If you can't find one, then look up the oxidation potential of each. Sometimes that is hard to find, too, so you look up the reduction table; i.e., Tl^+ + e ==> Tl and reverse the sign of the voltage generated. The higher the oxidation potential the more active the metal and the less stable. In fact, the activity series actually is an oxidation potential table. Let me know if you have any problems.
Seems I will have to do some (research) :-D
Thank you very much and sure I'll post again if I come up with problems regarding this.
