What was the problem with Dobereiner's periodic table?
Dobereiner's periodic table, proposed in the early 19th century, attempted to group elements into triads based on their similar chemical properties. However, this classification system was limited as it only included a few elements and did not account for all known elements at the time. Additionally, the triads were based on average atomic masses, which were not always accurate due to the existence of isotopes. This led to inconsistencies and inaccuracies in the arrangement of elements.
Who arranged the elements into triads?
Dmitri Mendeleev arranged the elements into triads in the periodic table. Mendeleev noticed that elements with similar properties occurred at regular intervals when arranged by increasing atomic mass.
What are the importance of the triads of Johann Dobereiner?
Dobereiner was a German scientist who was one of the first men to discover a pattern in elements ultimately leading to the periodic table you use in science today. Dobereiner saw a pattern in chemical properties of elements, he saw these patterns in threes. These groups are called Triads. Later he found physical property patterns as well.Hope this will help you.
What is the contribution of Dobereiner to the periodic table?
He provided the base for the classification of elements he says the elements are atomic masses nearly same he arranged the atomic masses of the middle element is approximately the arithmetic mean of other two elements,He first gave us the ''Law of Triads''...where he made lists of three elements each, and showed that the mass of the middle element is approximately equal to the average mass of the other two elements.
What periodic trends did Mendeleev organize his periodic table by?
Mendeleev organized his periodic table by atomic mass and similar chemical properties of elements to recognize patterns and trends. He arranged the elements in horizontal rows and vertical columns based on these properties, allowing him to predict the properties of undiscovered elements.
What periodic trends did did Mendeleev organize his periodic table by?
Atomic Mass Octaves and Triads
Which of the Dobereiner triads shown are still listed in the same column of the modern periodic table?
None of the Dobereiner triads are still listed in the same column of the modern periodic table. Dobereiner's triads were a set of three elements with similar chemical properties, but the modern periodic table is organized based on atomic number and electron configuration.
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.

What limitation of Johann Dobereiner in periodic table?
Dobereiner gave triads for few elements. It could not be applied to other elements.So it was not considered further.
Contribution of Johann Dobereiner for the periodic table?
An organized tabular arrangement of chemical elements on the basis of their electron configurations, atomic number and recurring chemical properties is the periodic table of elements. Johann Wolfgang Dobereiner has a great contribution in periodic table of elements because he foreshadowed the periodic law for the chemical elements.
How was Döbereiner's concept of triads an important step in the developement of the periodic table?
Döbereiner (working after 1815) was the first which found some rules for the rational arrangement of chemical elements. He proposed in 1829 the law of triads - only five triads were discovered.
Why did Dobereiner's triads table fail?
Dobereiner's triads table failed primarily because it was based on the observation of only a limited number of elements, which did not universally apply across the entire periodic table. His method of grouping elements into triads based on similar properties and their atomic weights did not consistently yield accurate predictions for all known elements. Additionally, as more elements were discovered, the relationships between atomic weights and properties became increasingly complex, highlighting the inadequacies of his approach. Ultimately, the development of a more systematic and comprehensive periodic table by later scientists, notably Mendeleev, rendered Dobereiner's triads obsolete.

Who preceded Mendeleev and Meyer with work on the periodic table?
Antoine Lavoisier and Johann Wolfgang Döbereiner made contributions to the development of the periodic table before Mendeleev and Meyer. Lavoisier proposed a classification system based on properties of elements, and Döbereiner developed the concept of triads, which grouped elements with similar properties.
