What were the limitations of Döbereiner’s classification?

Limitations of Döbereiner’s classification:

  1. They do not work at elements which have very low or high mass.
  2. All elements could not fit into Dobereiner’s traids.
  3. As the methods of calculating the atomic mass evolved, the authenticity of Dobereiner’s traids began to decline. For example, in the triad of F, Cl and Br, the arithmetic definition of the atoms of F and Br is not equal to the atomic mass of CI.
