What are the defects in mendeleev's periodic table?
His periodic was not in complete accordance with what he was classifying with i.e classification with respect to ascending atomic mass. here is an example: the atomic mass of the Ar is 39.9 and that of sodium is 39 but he placed Ar in the zero group and Na in the 1st group. this is one example. his periodic table had some more defects like this. this defect was observed when the true atomic masses were known. In his time the true atomic masses were not known. This was one of the reason for the failure of his periodic table.
