WebDobereiner Triads Rule In 1817, Johann Wolfgang Dobereiner, a German chemist, arranged the elements in the group of three elements and in a manner that the atomic mass of middle element was roughly the average of the atomic masses of the other two elements of the triad. Example: Average of the atomic masses of Lithium and Potassium is . WebSuch triads—including chlorine-bromine-iodine, calcium-strontium-barium, and sulfur-selenium-tellurium—were noted by the German chemist J.W. Döbereiner between 1817 and 1829. The triad was the earliest atomic-weight classification of the elements.
