Assertion (A) : In the periodic table of chemical elements, electron affinity is always found to increase from top to bottom in a group

Question

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 1

(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.
