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 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.
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.
Was there been more than one periodic table?
Yes, there have been several versions of the periodic table developed over time. The current version is based on Dmitri Mendeleev's layout, which arranges elements by their atomic number and chemical properties. Different scientists have made adjustments and improvements to the periodic table as new elements have been discovered.
Julius Lothar Meyer its contribution to the development of the periodic table?
Julius Lothar Meyer played a significant role in the development of the periodic table by independently publishing a periodic table of elements that showed the correlation between atomic volume and atomic weight. His work helped pave the way for the later development of the modern periodic table based on atomic number. Meyer's contribution, along with that of Dmitri Mendeleev, laid the foundation for our current understanding of the organization of elements.
Mendeleevs periodic table of elements was created in 1901?
Actually, Dmitri Mendeleev formulated the periodic law and published his periodic table of elements in 1869. This table arranged elements by increasing atomic mass and grouped them based on similar properties, predicting the properties of missing elements. It was a significant contribution to the field of chemistry.
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.
What did Johann Dobereiner do to try and sort out the elements on the periodic table?
Because he was a good scientist
Who among people that is responsible for the development of periodic table?
Dobereiner, Newland , Mendeleev are responsible for development. Modern periodic table was created by Henry Moseley.
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.
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.
How was the periodic table found?
the periodic table was was not found it was created by a few scientists names, Johann Dobereiner, Alexandre Beguyer de Chancourtois, Dimitri Mendeleev,Lord Rayleigh, William Ramsey, and Henry Moseley.
How was it hard to decide the periodic table?
Many attempts were made by Dobereiner , Newlands and Mendeleev in initial stages. Later on , the idea of arranging elements in increasing atomic number came up which is the today's periodic table.

What did Johannes dobereiner contribute to the atom?
Johann Döbereiner discovered patterns in atomic masses that foreshadowed the periodic table. Please see the link.
What is the contribution of Dmitri mendeleev?
he invented the first periodic table..
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.
