What is limitations of Dobereiner's classification? Related to ch=periodic classification of elements class 10 chemistry.?

Question

Answer

Answer

Limitations of Dobereiner’s Triads
The key shortcomings of Dobereiner’s method of classifying elements are listed below.

The identification of new elements made this model obsolete.
Newly discovered elements did not fit into the triads.
Only a total of 5 Dobereiner’s triads were identified.
Even several known elements did not fit into any of the triads.
Owing to these shortcomings, other methods of classifying elements were developed.

Answer

Answer

Limitations of Dobereiner's Classification

Dobereiner's classification was based on a limited number of elements. He only considered 30 elements.

The law of triads could not be applied to all known elements.

Dobereiner's classification was not able to explain the placement of elements in the same group. For example, why were chlorine and iodine placed in the same group despite having different properties?

It could not accommodate the discovery of new elements.

Dobereiner's classification did not provide a clear explanation of the relationship between atomic mass and chemical properties.

Dobereiner's classification was not able to explain the variation of properties within a group.

Relation to Periodic Classification of Elements

Dobereiner's classification was the first attempt to classify elements based on their properties.

It provided a basis for the development of the periodic table.

The limitations of Dobereiner's classification led to the development of more comprehensive periodic classification systems.

The periodic classification of elements is based on the arrangement of elements in order of increasing atomic number and the periodic repetition of their physical and chemical properties.

The periodic table provides a more comprehensive and accurate classification of elements than Dobereiner's system.

The periodic table has been able to accommodate the discovery of new elements and has provided a framework for understanding the behavior of elements in chemical reactions.

Overall, while Dobereiner's classification was an important first step in the classification of elements, its limitations ultimately led to the development of more comprehensive and accurate periodic classification systems.

Answer

The limitation of Dobereiner's classification of elements:

Dobereiner could identify only three triads from the elements known at that time. So, all the elements could not be arragneged in the form of triads on the basis of their similar chemical properties.

Answer

The main reason for the limitations of Dobereiner's classification is only three triads were made out of 33 known elements at the time.This was the main reason for the drawbacy of Dobereiner's law of triads.

Answer

Two important limitations are: All known elements could not be classified into groups of triads on the basis of their properties . Not all groups obeyed the Law of Triads. For example, nitrogen family does not obey the Law of Triads.
