WebThe rules of Dobereiner’s triads could not be applied to the elements which had very low or high atomic mass. Such as; if F, Cl and Br are put together in a triad, in increasing order of their atomic masses, the atomic mass of Cl is not an arithmetic mean of atomic masses of F and Br. After the advancement of techniques of measuring atomic ... WebDobereiner’s triads: In , Johann Wolfgang Dobereiner, a German chemist, proposed grouping elements based on their relative atomic masses. He organised three elements into each group. He referred to these groups as 'triads' (tri-three). When the elements in a triad are arranged in ascending order of their atomic masses, Dobereiner discovered ...
