NEET Chemistry Periodic Table Assertion Reason Question
Assertion (A): The inner transition series elements are placed separately to maintain the Periodic Table's structure.
Reason (R): The principle of classification is preserved by grouping elements with similar properties in a single column.
Both A and R are true, and R is the correct explanation of A.
