The merits are :
1)Mendeleev left gaps for the new elements to be discovered in future
2)He also predicted the properties and atomic masses of the elements to be discovered in future
3) The noble gases were discovered very late as they are very inert. When they were discovered, they could be placed in a new group in the table without disturbing the existing order.....

MERITS ARE
1. The classification of elements is based on the atomic number, which is a more fundamental property.
2. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic number.
3. It explains the periodicity of the properties of the elements and relates them to their electronic configurations.
5. The position of the elements that were misfits on the basis of mass number (anomalous pairs like argon and potassium) could be justified on the basis of atomic number.
6. The lanthanides and actinides are placed separately at the bottom of the periodic table.
7. The table is simple, systematic and easy way for remembering the properties of various elements as it is based on the electronic configuration.
And
Demerits are:-
1. Position of Hydrogen is still in dispute to keep weather in Alkali, Crystallogens ,or Halogen
2. Lanthanides and Actinides are kept away from main body
