Why Doberniers Triads became failed? |
|
Answer» Drawbacks of Dobereiner\'s classification of elements was that it\xa0failed\xa0to arrange all the then known elements in the form of\xa0triads\xa0of elements having similar chemical properties. ... Dobereiner also\xa0failed\xa0to explain the relation between atomic masses of elements and their chemical properties. Limitations of Dobereiner’s classification of elements was that it failed to arrange all the then known elements in the form of triads of elements having similar chemical properties. His classification was not applicable to all known elements but was limited only to a few elements. For example: nitrogen, Phosphorus and arsenic have similar chemical properties but they do not constituent a Dobereiner’s triad. Dobereiner’s could identify only three triads from the elements known at that time. So his classification of elements was not much successful. Dobereiner also failed to explain the relation between atomic masses of elements and their chemical properties.\xa0 Doberneir traid was got failed because his law was not applicable for all the elements... |
