Question

Explain in brief about Dobereiner's Triads.

(mention all 3triads and the relationship between them)​

Answer 1

Answer:

Dobereiner's triads were groups of elements with similar properties that were identified by the German chemist Johann Wolfgang Dobereiner. He observed that groups of three elements (triads) could be formed in which all the elements shared similar physical and chemical properties.

Step-by-step 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. ... Three more triads were identified by the year 1829.

Answer 2

Step-by-step explanation:

In 1829, a German chemist, Johann Dobereiner (1780–1849), placed various groups of three elements into groups called triads. One such triad was lithium, sodium, and potassium. ... Dobereiner found that the atomic masses of these three elements, as well as other triads, formed a pattern.
