He found that the atomic mass of the middle element was approximately equal to the arithmetic mean (average) of the atomic masses of the other two elements of that triad when they are arranged in their increasing order of atomic mass, e.g., Li, Na, K.
NettetSolution. Dobereiner's law of triads: When elements are arranged in order of increasing atomic masses,groups of three elements (triads), having similar chemical properties are obtained.
