⏩ When Nobel gas were discovered, they could be placed in a new group without disturbing existing order.
✔️ Limitations of Mendeleev's Periodic Table :-
⏩ No fixed position was given to hydrogen in the Periodic Table.
⏩ Isotopes were discovered long after Mendeleev had proposed periodic classification of elements. Isotopes of all elements posed a challenge to Mendeleev's Periodic Table.
