Question

Whatn are limitations in Mendeleeff's periodic table ?​

Answer 1

♦ LIMITATIONS OF Mendeleev's Periodic Table ♦ :-

➡ Position of Hydrogen => Position of hydrogen in the perodic table is Uncertain , Because hydrogen is placed in 1 A group with Alkali metals .

➡ Position of isotopes => isotopes haven't been given separate place in perodic table .

➡ Cause of periodicity => Mendeleev could not explain the cause of periodicity .

➡ Separation of similar elements => some dissimilar elements have been placed together

Hope this works out.....
