Did dobereiner triads also exist
WebYes, Dobereiner's triads also existed in the columns of Newlands' law of octaves. This can be explained by taking the second column of the Newlands' classification of elements as an example. The second column has the elements lithium (Li), sodium (Na) and potassium (K), which form a Dobereiner's triad. WebLimitations of Dobereiner’s classification: 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’s could not be classify most of the elements known at that time.
