1.	Consider the following statements and select the correct code. Assertion (A) : In the periodic table of chemical elements, electron affinity is always found to increase from top to bottom in a group Reason (R) : In a group, the atomic radii generally increase from top to bottom. (a) Both A and R are individually true and R is correct explanation of A (b) Both A and R are individually true and R is not the correct explanation of A (c) A is true but R is false (d) A is false but R is true
Answer» (d) A is false but R is true Explanation: Electron affinity generally decreases from top to bottom in a group. Atomic radii increases from top to bottom as energy levels increases because as we move down a group number of electrons increases.
