Question

what was drawback of medeleeve's law?​

Answer 1

Answer:

There was no place for new elements.

Explanation:

The position of hydrogen was not defined correctly as it resembled few characteristics of alkali metals and few of halogens. Position of isotopes would be different according to Mendeleev's periodic table. No separate positions were given to lanthanoids and actinoids. Position of group VIII elements was not justified.
