Question

Merits ot modern Table ........................ and Advantages of Modern Table

Answer 1

Hey there!

MERITS ARE

1. The classification of elements is based on the atomic number, which is a more fundamental property.

2. The reason for placing isotopes at one place is justified as the classification is on the basis of atomic number.

3. It explains the periodicity of the properties of the elements and relates them to their electronic configurations.

5. The position of the elements that were misfits on the basis of mass number (anomalous pairs like argon and potassium) could be justified on the basis of atomic number.

6. The lanthanides and actinides are placed separately at the bottom of the periodic table.

7. The table is simple, systematic and easy way for remembering the properties of various elements as it is based on the electronic configuration.

Advantages

1.This classification is based on the atomic number which is a more fundamental property of the elements.

2.Since this classification is based on the atomic number and not on the atomic mass, the position of placing isotopes at one place is fully justified.

3.It is easy to remember and reproduce.

4.The systematic grouping of elements into four blocks; s, p, d and f has made the study of the elements more simple.

5.The position of some elements which were misfit on the basis of atomic mass is now justified on the basis of atomic number. For example, argon precedes potassium because argon has atomic number 18 and potassium has 19.

6.The lanthanoids and actinoids which have properties different from other groups are placed separately at the bottom of the periodic table.
