WebIn 1829, a German chemist, Johann Dobereiner (1780–1849), placed various groups of three elements into groups called triads. One such triad was lithium, sodium, and potassium. Triads were based on both physical as well as chemical properties. Dobereiner found that the atomic masses of these three elements, as well as other triads, formed a … 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.
