Question

Disscuss briefly the factor affecting electron affinity

Answer 1

atomic radius will affect electron affinity

Answer 2

The factors affecting the electron affinity are as follows:-

--»Atomic size :-
If the atomic size increases the attraction of the nucleus on the adding electron decreases ,, electron affinity.
--»Nuclear charge :-
Nuclear charge is directly proportional to electron affinity....
--»Screening effect :-
Screening effect is inversely proportional to electron affinity........
--»Electronic configuration :-
Half filled and completely filled electronic configuration are stable and they have less affinity to accept electrons , so the electron affinity values of those electronic configuration contain elements are very less or almost zero .........
