How can you tell a substance is amphoteric by just looking at it? or is there a way you can figure it out?

Oxides formed by metalloids in the diagonal band are often amphoteric, such as barium oxides, aluminum oxides, gallium (Ga) oxides, tin (Sn) oxides, antimony (Sb) oxides and lead oxides.

Amphoteric substance is a molecule/ion that can act either as an acid or base. They should have transferable H and atom with lone pair electrons.

I believe that there is some sort of pattern on the periodic table which begins with Be and goes diagonal downwards ending in Bi. This would be in the case of Oxides.
