Answer» Arrangement of elements in triads of three elements in which elements are placed increase in atomic masses where atomic mass of second element was roughly the average of first and third element. triads were arranged such that at. mass of middle element is the mean of other two elements Johann Wolfgang Döbereiner, a German chemist, tried to arrange the elements with similar properties into groups. He identified some groups having three elements each. So he called these groups triads. Döbereiner showed that when the three elements in a triad were written in the order of increasing atomic masses; the atomic mass of the middle element was roughly the average of the atomic masses of the other two elements. OK thanks Increasing atomic mass Plz give answer anyone... |
