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.
