What is meant by the term bond order ? Calculate the bond order ? Calculate the bond order of : `N_(2),O_(2),O_(2)^(-)and O_(2)^(2-)`

Explanation

### Step-by-Step Solution

1. **Definition of Bond Order**:
- Bond order is defined as the number of chemical bonds between a pair of atoms. It indicates the stability of a bond; higher bond order means a stronger bond.
- Mathematically, bond order can be calculated using the formula:
\[ \text{Bond Order} = \frac{1}{2} \times (\text{Number of bonding electrons} - \text{Number of antibonding electrons}) \]
