Advantages of dmitri mendeleev's periodic table

Answer 1

1 Mendeleev made the first attempt to arrange the elements in systematic way i.e in groups and period
2He also predicted some new elements and left space in his periodic table
3 He also made corrections in doubtful atomic mass of some elements like Beryllium

Answer 2

Answer:

Mendeleev’s periodic table is, more accepted for its originality and boldness in making corrections in the properties and predicting unknown elements.

Mendeleev was the first one to establish a systematic arrangement and bring out the periodicity of properties of elements with atomic weight and propose a periodic law.

It could point out the incorrect atomic weight of some elements known at that time.

It could predict the existence of other elements and could predict their properties so, as to leave space in the periodic table.

It could accommodate all the sixty elements discovered at that time and could accommodate the noble gases which, where discovered later.
