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.

Johann Dobereiner placed elements with similar properties in to groups of threes called what?
triads
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.
Who arranged the elements into triads?
The scientist who arranged the elements into triads was Dobereiner.
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
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.
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.
Who arranged atom in the form of triads'?
Johann Wolfgang Dobereiner,a German chemist arranged atom in the form of triads in 1817.
What was the exact date of johann dobereiner's discovery?
Johann Wolfgang Döbereiner discovered the concept of the law of triads in 1817.
Johann Dobereiner placed elements with similar properties in to groups of threes called what?
triads
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)
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.

Who arranged the elements into triads?
The scientist who arranged the elements into triads was Dobereiner.
Who are the parents of Johann Dobereiner?
Johann Wolfgang Dobereiner was a German chemist. His father was Johann Adam Dobereiner and his mother was Johanna Susanna Goring.
Who preceded Mendeleev and Meyer with work on the periodic table?
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
Where did Johann Dobereiner live?
Germany
What did Johann dobreiner do for the periodic table?
