Dobereiner’slaw 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.

What do you mean by law of triad?
According to the law of triads, when elements are arranged in increasing order of their atomic masses, the arithmetic mean of the atomic masses of the first and third element in a triad is approximately equal to the atomic mass of the second element in that triad. Question 2: What do you mean by triad in reference to Dobereiner triads?
What is Dobereiner’s law of triads?
Dobereiner’s law of triads also stated that the atomic masses of the first and third elements in the triad would be approximately equal to the atomic mass of the second element in the triad. Also, he suggested that this particular law could be extended for the other quantifiable properties of elements such as density.
What is a triad of elements?
He observed that groups of three elements (triads) could be formed in which all the elements shared similar physical and chemical properties.
Can Dobereiner鈥檚 triads group elements according to their properties?
Although Dobereiner鈥檚 triads could not group all elements according to their properties it said the foundation for the formation of the modern periodic table. Question 1: What is the law of triads?
