But this classification into triads was not found to be useful. In 1866, Newlands arranged the then known elements

WebDobereiner 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.

WebAlso the properties of the middle element were in between those of the other. two members. Since Dobereiner’s relationship, referred to as the Law of Triads, seemed to work only for a few elements, it was dismissed as coincidence. The next reported attempt to classify elements was made by a French geologist, A. de Chancourtois in 1862.
