Since, Tellurium(H2TeO3) is lesser electronegative than H2Se3, H2Se4, and H2T3O & H2Se3, H2Se4, and
H2T3O dissociates more readily than H2TeO3 , therefore these are stronger acid than H2TeO3.
Tip:: Moving from left to right across a row on the Periodic table elements become more electronegative (excluding the noble gases), and the strength of the binary acid formed by the element increases accordingly:
