Did dobereiners triads also exist in the columns newlards octaves?
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.
Did scientists support Dobereiners theory?
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.
What are the advantage of law of triads?
The law of triads helped in identifying patterns and relationships among elements, leading to the development of the periodic table. It also played a key role in the early classification of elements based on their atomic masses and properties. However, the law of triads was later superseded by more accurate and comprehensive periodic table arrangements.
Why dobereiners triad was rejected?
Döbereiner's triads were rejected because they did not work for all elements and their properties as more elements were discovered. They were limited to grouping only a few elements with similar properties, and the periodic table provided a more comprehensive and accurate organization of elements based on atomic number and properties.
What are the merits and demerits of dobereiner law of triads?
The merit of Dobereiner's Law of Triads is that it recognized patterns in chemical properties of certain elements and grouped them together based on similarities. However, a major demerit is that it was limited in its application and only applied to a few elements, making it less useful as more elements were discovered that did not fit into triads.
What Resulted from the first experimental effort that established the idea of group of elements?
The Law of triads
What were the limitations of Dobereiners classification?
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.
What was the exact date of johann dobereiner's discovery?
Johann Wolfgang Döbereiner discovered the concept of the law of triads in 1817.
What is the relationship between the Triads or similar Chinese criminal organisations and the State of Israel or Jewish Zionism?
There is no link between the Triads or any criminal Chinese enterprises and the State of Israel. There may possibly be connections between Mossad and the Triads since many Intelligence Agencies blur the line between covert operations and actual crime, but there is no historical or explicit connection between these two groups.
What are dobereiner's triads defect?
the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
What are the kinds of triads?
There are four types of triads: major, minor, augmented, and diminished. Major triads consist of a root, major third, and perfect fifth. Minor triads have a root, minor third, and perfect fifth. Augmented triads have a root, major third, and augmented fifth. Diminished triads have a root, minor third, and diminished fifth.
What did Johann dobreiner do for the periodic table?
Dobereiner classified elements into groups of three. He introduced law of triads according to this law every element which comes in the middle of such a group has atomic mass equal to average of the atomic masses of first and third element. for example Lithium(Li) 7 Sodium(Na) 21 Potassium(K) 39
