Question

give two drawbacks (limitations) of mendelevs periodic table

Answer 1

Hii.....
The two drawbacks of Mendeleev's periodic table are....
1. Hydrogen showed both properties alkali metals as well as halogens so no fixed position could be given to hydrogen...
2. Cobalt(Atm.weight-27.71) was placed before Nickel (Atm. weight - 27.59) though he adopted the principle of placing elements in increasing order of atomic mass.....

Hope this helps you...... ☺
