Question

hyyyyy,characteristics of mendeleev's preodic table?​

Answer 1

Answer:

Characteristics of Mendeleev's periodic table are:-

1.He examined the relationship between the atomic masses of the elements and their physical and chemical properties.

2.Among chemical property,Mendeleev concentrated on the compounds formed by elements with oxygen and hydrogen.

3.He selected hydrogen as they are very reactive and formed compounds with most elements.

4.He arranged them according to their atomic mass.It was observed that not only the chemical but physical properties recurred at equal interval.

5.The formula of oxides and hydrides formed by an element were treated as one of the basic properties of an element fir it's classification.

6.Elements with similar properties should be grouped together.

7.Some gaps were left for the undiscovered elements.

8.Nobel(inert)gases could be placed without disturbing the existing order.

Answer 2

answer:

1) The table is divided into 8 groups and 7 periods. 2) Elements are arranged in vertical columns according to their periodic properties. 3) Mendeleev did not leave any gap for the elements to be discovered in future. 4) Elements are placed according to the periodic function of their atomic masses

hope it helps✌✌
