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 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.
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 However, the law of triads was later superseded by more accurate and comprehensive periodic table arrangements.
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.
What are the merits and demerits of dobereiner law of triads?
The merit of Dobereiner's Law of Triads is that it recognized patterns in chemical properties of certain elements and grouped them together based on similarities. However, a major demerit is that it was limited in its application and only applied to a few elements, making it less useful as more elements were discovered that did not fit into triads.
What Resulted from the first experimental effort that established the idea of group of elements?
