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]`?

Options

A. `O^(x)`
B. `O^(y)`
C. `O^(z)`
D. All have equal.

Explanation

To determine which of the species \( O^x, O^y, O^z \) (where \( x = 0, y = -1, z = -2 \)) has the maximum value of electron affinity, we need to analyze each species:

1. **Identify the species**:
- \( O^0 \) is the neutral oxygen atom (O).
- \( O^{-1} \) is the negatively charged ion (O⁻).
- \( O^{-2} \) is the doubly negatively charged ion (O²⁻).

2. **Understand electron affinity**:
...
