NEET Chemistry Periodic Table Assertion Reason Question
Assertion (A): The 4f-inner transition series of elements is placed separately in the Periodic Table.
Reason (R): This arrangement helps in maintaining the structure of the Periodic Table by keeping elements with similar properties in a single column.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
