A lithium atom can also achieve only a duplet and never an octet. Dobereiner's law of triads failed for the following reasons: All the known elements found later could not be arranged in the form of triads. For very low mass or for very high mass elements, the law was not holding good.

Answer 2

Answer:

The basis of classification of Dobereiner 's traids is atomic mass. Dobereiner arranged elements in the form of triads.In each triad the elements are arranged in increasing order of their atomic mass. The atomic mass of the middle element is equal to the average atomic mass of both the terminal elements.
