Answer 1

noble gases got a place without changing disturbance in modern periodic table . also 118 elements successfully fit in it as atomic number was taken into consideration

Answer 2

merits given below

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

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

3.It is easy to remember and reproduce.

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

4.The position of some elements which were misfit on the basis of atomic mass is now justified on the basis of atomic number. eg .anomalous pairs like argon and potassium

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