Answer 1

The merits of the Modern Periodic Table of Elements are as follows:
 1. It is based on the atomic number of elements.
 
 2. The modern periodic table clearly explains the reason behind elements showing similar properties in a group and dissimilar properties in different groups.
 
 3. This also explains the reason for the periodicity in the properties of elements.
 
 4. The modern periodic table explains the reason for a repetition in the properties of elements after 2,8,18 and 32 elements.
 
 5. In the modern periodic table, there are no anomalies in the arrangement of elements.
