A skeletal structure for sulfurous acid (H₂SO₃) shown below. Starting from this structure, complete the Lewis structure that follows the octet rule on all atoms.

## Sulfurous Acid (H2SO3) Lewis Structure

### Introduction
The skeletal structure for sulfurous acid (H₂SO₃) is shown below. This structure is a basis to help you complete the Lewis structure that adheres to the octet rule for all atoms.

### Instructions
Starting from this structure, complete the Lewis structure that follows the octet rule on all atoms.

### Skeletal Structure
Below is the initial skeletal structure of the sulfurous acid molecule:

- **Sulfur (S)**: The central sulfur atom is bonded to three oxygen (O) atoms.
  - **Double Bond**: One oxygen atom forms a double bond with the sulfur atom, contributing two pairs of electrons in the bond.
  - **Single Bonds**: The other two oxygen atoms form single bonds with the sulfur atom. These oxygen atoms each have a hydrogen (H) atom attached.
- **Hydrogen (H)**: There are two hydrogen atoms, each bonded to a different oxygen atom.

### Step-by-Step Guide to Completing the Lewis Structure:
1. **Identify Valence Electrons**: 
   - Sulfur: 6 valence electrons
   - Oxygen: 6 valence electrons each
   - Hydrogen: 1 valence electron each

2. **Determine Total Electrons**:
   - Total valence electrons = 1(2) + 6(3) + 6 = 24 electrons

3. **Draw Skeletal Structure**:
   - Place sulfur (S) in the center.
   - Attach each oxygen (O) to sulfur with single bonds.
   - Attach one hydrogen (H) to each of the two single-bonded oxygen atoms.

4. **Distribute Remaining Electrons to Fulfill Octet Rule**:
   - Distribute electrons around each oxygen to complete their octets. 
   - Add double bonds if needed to ensure sulfur follows the octet rule.

### Conclusion
Completing the Lewis structure ensures that the octet rule is satisfied for all atoms. This representation helps in understanding the electron configuration and the bonding nature in sulfurous acid molecules. If you have any questions or need further clarification,
