write down the dobereiner classification or law of roleof traid ?
New land law
Dobereiner's classification, which grouped elements into triads based on similar properties, had several limitations. It only encompassed a small number of elements, primarily focusing on the known elements at the time, which were insufficient to represent the entire periodic table. Additionally, not all elements could be neatly categorized into triads, and it failed to account for the periodicity of properties across larger groups of elements. This classification system was ultimately superseded by more comprehensive frameworks, like Mendeleev's periodic table.
No, Dobereiner's triads were a set of three elements with similar properties where the atomic mass of the middle element was approximately the average of the other two. Newlands' Octaves, on the other hand, arranged elements in rows of seven, where every eighth element showed similar properties. These two classification schemes were different from each other.
difference between knowledge classification and book classification?
Some scientists supported Johann Dobereiner's theory of triads, which suggested that certain elements had similar properties and could be grouped together. However, the theory was later replaced by the modern periodic table developed by Dmitri Mendeleev.
