Text Solution

Verified by Experts

He classified in group of three such that atomic No. of middle elements is average of first and third element. Eg: Li(7), Na(23), K(39), Limitations :
* Dobereiner could find only three triads, i.e. total of 9 elements only.
* However the total number of elements were more than that of those encompassed in Dobereiner.s triad.
* Thus Dobereiner could not classify most of the elements known at that time..
