The Characteristics of Mendeleev's Periodic table are as follows:
- The elements were arranged on the basis of increasing atomic masses.
- Mendeleev left some gaps for the elements which were not known at that time.
- The discovery of new elements like inert gases did not disturb his periodic table.
- The properties of several elements like Scandium,Gallium and Germanium could be predicted because of placement of new elements in the periodic table.
