Question

What are the he advantages of Mendeleev periodic law

Answer 1

Answer:

Advantages

1) 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.

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

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

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

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.
