No fixed position could be assigned to hydrogen in the Periodic Table.
Isotopes discovered long after Mendeléev periodic classification of
elements imparted a challenge to Mendeleev’s Periodic Law.
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.
