Question

Explain Mendeleev’s periodic table. Give Limitations of Mendeleev’s periodic

table.​

Answer 1

Answer:

LIMITATIONS OF Mendeleev's Periodic Table : ... 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 .

Answer 2

Answer:

Mendeleev's periodic table is an arrangement of elements in an increasing atomic mass order in a tablet form, such that it reflects similarities and trends in the behaviour of elements.

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 .
