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.
Dobereiner's periodic table had limitations because it only grouped elements into triads based on similar chemical properties, without considering atomic number or structure. This led to inconsistencies when new elements were discovered that did not fit into his triads. As a result, the concept was eventually replaced by more modern periodic table arrangements.
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.

Did scientists support Dobereiners theory?
Some scientists supported Johann Dobereiner's theory of triads, which suggested that certain elements had similar properties and could be grouped together. However, the theory was later replaced by the modern periodic table developed by Dmitri Mendeleev.
What is the name of the table of elements?
The table of elements is called the Periodic Table of Elements. It organizes all known chemical elements based on their atomic number and chemical properties.
What is a group in a periodic table.?
A group in Periodic Table is the column of element in periodic table

It is called the Periodic Table of Elements.
What are chemical compounds on the periodic table?
There are no compounds on the periodic table. The periodic table only lists elements.

Which can be found on a periodic table elements compounds or mixtures?
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
