Which of the following species have same bond order and same shape
(a) `N_(3)^(Θ)` (b) `O_(3)` (c ) `CO_(2)` (d) `NO_(2)^(Θ)`.

Explanation

To determine which of the given species have the same bond order and the same shape, we will analyze each species in terms of their valence electrons and molecular geometry.

### Step 1: Count the Valence Electrons

1. **For N₃⁻ (Azide ion)**:
- Nitrogen (N) has 5 valence electrons.
- There are 3 nitrogen atoms: 3 × 5 = 15 electrons.
- Add 1 for the negative charge: 15 + 1 = 16 valence electrons.
