Question

Which property did Dobereiner use to classify the elements ? Give
example.

Answer 1

Dobereiner's Law of Triads. Dobereiner, in 1817 suggested a relationship between the properties of elements and their atomic weights. Johann Wolfgang Dobereiner. According to Dobereiner, the atomic weight of the middle element is nearly the same as average of the atomic weights of other two elements.

Answer 2

Dobereiner use the property of increasing atomic mass of elements. He classify three elements together having similar properties and called it as triads.
For example the elements having lower atomic mass are placed before than elements having higher atomic mass.
Eg Li-7 Lithium have atomic mass as 7
Na-23 Sodium has atomic mass as 23
K-39 Potassium have atomic mass as 39
The main thing about these traids is that the atomic mass and property of middle elaments is equal to the average of atomic mass and property of other two elements.
