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.
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.
The scientist who arranged the elements into triads was Dobereiner.
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.
triads
In 1817, a German chemist, Johann Wolfgang Dobereiner tried to arrange the elements with same properties into groups. He found out that some groups had only 3 elements and called them 'Triads'. He showed that when the 3 elements were written in their order of increasing atomic masses……the atomic mass of the middle element was roughly* the average of the masses of the other two elements.For example:Li Na K6.9 23.0 39.0Average of Li & K = 22.95, i.e., *roughly 23.0But since all the elements known then also couldn't be classified as this......'Dobereiner's Triads', as the table is known……wasn't useful……but the attempts of Dobereiner encouraged other chemists to correlate the properties of elements with their atomic masses.Sidz
Johann Wolfgang Dobereiner was a German chemist. His father was Johann Adam Dobereiner and his mother was Johanna Susanna Goring.
write down the dobereiner classification or law of roleof traid ?
Dobereiner gave triads for few elements. It could not be applied to other elements.So it was not considered further.
Newlands and Dobereiner. Newlands did the Law of Octaves. Dobereiner did the Triads.
Dobereiner tried to discover a rational classification of chemical elements.
Germany
the main defect of' dobereiner's triads is that he put the chemically dissimilar elements in the same triads (dahal.ramchandra@gmail.com)
