1.	Which will have the maximum value of electron affinity `O^(x),O^(y),O^(z)` [x,y and z respectively are `0,-1` and `-2]`?A. `O^(x)`B. `O^(y)`C. `O^(z)`D. All have equal.
Answer» Being neutrai atom oxygen will have higher electron affinity as there is electrostatic repulsion between additional electron and negative ion in case of `O^(-)` and `O^(2-)`. So option `(A)` is correct.
