Why do transition metals form +1/+2 ions preferentially?

Homework Statement

Why do transition metals tend to form +1/+2 ions? Take electron configurations into account so that I can better understand this "easy" concept.2. The attempt at a solution
I think it has to do with the s orbitals. These, I think are valence electrons that are easily lost... most have 2 s electrons at a high energy level, so it makes sense to lose those first.

Thanks for the help!
