WebDobereiner proposed that all elements could be grouped in such triads, but subsequent attempts to expand his concept were unsuccessful.

WebIn 1829, a Germen chemist Dobereiner observed that certain elements have similar properties, and he put such elements in the group of threes These groups of three elements are called triads. All the elements of triad had similar chemical properties. Dobereiner was the first to show the relationship between the properties of elements http://chemed.chem.purdue.edu/genchem/history/dobereiner.html
WebFor a Dobereiner's triad, all the three elements should belong to the same group, and the difference in atomic number should be 8 or 18. Newlands Law of Octave In 1866, J.A.R. Newlands correlated the chemical properties of the elements with the increasing order of atomic masses. i.e. to place the element having the lowest atomic mass (H) at the first … WebDobereiner arranged a group of three elements with similar properties in the order of increasing atomic masses and called it a triad. He showed that the atomic mass of the middle element is approximately the arithmetic mean of the other two. But, Dobereiner could identify only the following three triads from the elements known at that time.
