Draw the resonating structure of
(i) Ozone molecule
(ii) Nitrate ion.

Explanation

To draw the resonating structures of the ozone molecule (O3) and the nitrate ion (NO3-), we will follow these steps:

### Step 1: Draw the Lewis Structure of Ozone (O3)
1. **Count the Valence Electrons**: Each oxygen atom has 6 valence electrons. For three oxygen atoms, the total is 6 x 3 = 18 valence electrons.
2. **Arrange the Atoms**: Place one oxygen atom in the center and the other two on the sides.
3. **Connect the Atoms**: Draw a double bond between the central oxygen and one of the outer oxygen atoms, and a single bond (which can also be considered a coordinate bond) between the central oxygen and the other outer oxygen atom.
4. **Distribute Remaining Electrons**: Place the remaining electrons to satisfy the octet rule for each oxygen atom.
