NEET Chemistry Periodic Trends Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
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.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
