What is the limitations of mendeleef periodic tablet |
|
Answer» \tNo fixed position could be assigned to hydrogen in the Periodic Table.\tIsotopes discovered long after Mendeléev periodic classification of\telements imparted a challenge to Mendeleev’s Periodic Law.\tThe 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. Could not assign correct position to hydrogen, position of isotopes could not be explained and wrong order of atomic masses of some elements could not be explained. |
