Example of dobereiner's triad
WebDobereiner's Triad Dobereiner arranged the element in increasing order of atomic masses. 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. WebThis was known as the Dobereiner's law of triads. The law states that when elements are placed in the ascending order of atomic masses, groups of three elements having similar …
