Solution

Advantages of Mendeleev's periodic table:
Prediction of new elements: The existence and properties of elements that are similar to Boron/Aluminum/Silicon is predicted by Mendeleev.
He left the gap after some elements and gave them hypothetical names such as Eka-Alumium/Eka-Silicon.
He took more similarities in properties than to atomic mass in the arrangement such as Iodine $(I)$ has a smaller weight than Tellurium $(Te)$ but it was placed after it.
From the periodic properties, Beryllium $(Be)$ , Indium $(In)$ , Gold $(Au)$ , and Platinum $(Pt)$ were predicted to be having inaccurate mass which lead to the re-estimation of their real masses.
Mendeleev could accommodate all the sixty elements discovered at that time and could accommodate the noble gases which, were discovered later.
His table could point out the incorrect atomic weight of some elements known at that time.
