Achievements of Dobereiner's triads :
Dobereiner, a German scientist, was the first to classify elements into groups based on John Dalton's assertions. He grouped the elements with similar chemical properties into clusters of three called 'Triads'. The distinctive feature of a triad was the atomic mass of the middle element. When elements were arranged in order of their increasing atomic mass, the atomic mass of the middle element was approximately the arithmetic mean of the other two elements of the triad.It made a look at elements in terms of groups of elements with similar chemical and physical properties. This eventually led to rigorous classification of elements and the modern periodic table of elements, as we now know it, was discovered

In 1817 a German chemist tried to arrange the elements in periodic table into groups.He arranged the elements according to increasing atomic mass.
He arranged the elements into groups each group has three elements. so He called that groups as" triads"..
He arranged elements in these groups as the average of first and third element is equal to the middle element..
