Limitations of Dobereiner's triads:

  • He could classify the elements only into 3 triads.
  • He was not able to prepare triads for all known elements which were present at that time.

Characteristics of Dobereiner's triads:

  • Elements which had similar chemical properties were placed in the same group.
  • He arranged elements on the basis of their increasing order of atomic masses.
  • He arranged elements such that the sum of atomic masses of first and last elements was approximately the average of middle element.

Example:

Lithium → 7

Sodium → 23

Potassium → 39

Atomic mass of Sodium = (7 + 23) ÷ 2 which is approximately equal to 23.
