Question

write down the limitation of mendeleev's periodic table​

Answer 1

Answer:

limitations are given below

Explanation:

(i) He could not assign a correct position of hydrogen in his periodic table, as the properties of hydrogen resembles both with alkali metals as well as with halogens.

(ii) The isotopes of the same element will be given different position if atomic number is taken as basis, which will disturb the symmetry of the periodic table.

(iii) The atomic masses do not increases in a regular manner in going from one elements to the next.

Answer 2

It does not specify the position of hydrogen.

Elements with different properties were included in the same group.

The increasing order of mass was not followed.

Mendeleev couldn't explain periodicity.

Isotopes were not given a place in the periodic table.
