NEET Chemistry Periodic Trends Assertion Reason Question
Assertion (A): Electronegativity decreases down a group in the periodic table.
Reason (R): The increase in atomic and ionic radii down a group leads to a decrease in non-metallic properties of elements.
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
Both the assertion and reason are true. The decrease in electronegativity down a group is due to the increase in atomic and ionic radii, which results in a decrease in non-metallic properties of elements.
