1. in his table place for hydrogen was not specified
2. his table was in increasing atomic masses order but Cobalt and Nickel was not in this order
please mark it has brainliest

1) Isotopes discovered long after Mendeléev periodic classification of
elements imparted a challenge to Mendeleev’s Periodic Law.
2)The atomic masses of elements did not increase in a steady manner while going from one element to other which made it difficult to predict the number of elements that could be discovered between two elements.

>MENDELEEV arranged elements in ascending order of their "atomic masses" and found that elements having similar chemical properties appeared at regular intervals while after the discovery of atomic number it was noticed that elements could be classified more.satisfactorly by "atomic number."
>There was also the addition of an extra group(group8A) at the extreme right of the periodic table which contains NOBLE GASES which had not been discovered at MENDELLEVE,S TIME
