limitation of dobereiner of periodic table
Answers
Hi frnd...
LIMiTATIONS OF DOBERIENER PERIODIC TABLE:
Dobereiner could find only three triads total of 9 elements only. However the total number of elements were more than that of those encompassed in Dobereiner's Triad.
Thus, Dobereiner's could not be classify most of the elements known at that time.
Dobereiner was the first to arrange the Elements with similar properties into groups.
He showed that when the Elements in a triad were written in their increasing atomic masses, the atomic mass of the middle element was almost equal to the average of the atomic masses of other two Elements. So, it was known as Dobereiner's Triads
The limitation of doberenier's Triads was ::-
Doberenier could identify only 3 Triads from the Elements known as that time . Hence this system of classification of elements into form of Triads was not useful.
