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. The atomic mass of the middle elements of the triad being equal to the arithmetic mean of the atomic masses of the other two elements.
For example: Alkali metal group ( Dobereiner's triad) : Lithium is the 1st element, sodium is the middle element whereas potassium is the 3 rd element of the triad.
the arithmetic mean of the atomic masses of the first and third element in a triad would be approximately equal to the atomic mass of the second element in that triad
Explanation:
Dobereiner stated in his law of triads that the arithmetic mean of the atomic masses of the first and third element in a triad would be approximately equal to the atomic mass of the second element in that triad.
