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 is remembered for what were called "Dobereiner's Triads" which are groups of three elements having similar chemical properties. This is a forerunner of the periodic table, but it is not actually a table, and it does not offer any explanation for the chemical similarities observed within the triads. Mendeleev's Periodic Table of the Elements shows the relationship of every element to every other element, and explains why they all have the chemical properties that they have.
Was there been more than one periodic table?
Before the modern periodic table , the concepts for classification of elements were given by Dobereiner , Newland law of octaves ,Mendeleev's periodic table.
Who was Dobereiner?
johann dobereiner had contributed towards the base of the periodic table and discovered that the elements shared similiar properties because there always was three elementzs in three groups that he later refered to as Triads.
What is the major contribution of Dmitri Mendeleev to science and society?
He created the periodic table.
Julius Lothar Meyer its contribution to the development of the periodic table?
Julius Lothar Meyer devised a classification of elements into a table that accounted for the periodic variation in properties. his table included 56 elements.
Who preceded Mendeleev and Meyer with work on the periodic table?
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.

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.
What is the correct chronological order of scientists contributing to the modern periodic table?
Lavoisier, Dobereiner, Newlands, Mendeleev, and Moseley
Who was Dobereiner?
johann dobereiner had contributed towards the base of the periodic table and discovered that the elements shared similiar properties because there always was three elementzs in three groups that he later refered to as Triads.
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.
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.
What did Johannes dobereiner contribute to the atom?
Johann Döbereiner discovered patterns in atomic masses that foreshadowed the periodic table. Please see the link.
