I dont believe you. What about Hydrogen compounds, odor,  Oxides behaviour dissolved in water. Heavy metal compounds, colour , where can be found? High oxidation number ions and salts, acids, and more

Those are all characteristics that make them different not them same in one aspect and I don't understand the part where you say "I don't believe you" because it is a question not a statement.

No the opposite is the case. Compare H₂S, H₂Se and H₂Te
What about H₂SO₄ and H₂SeO₄ ,SO₂, SeO₂

Me_xS_y, Me_xSe_y, Me_xTe_y also Me_xO_y => ore
