How are the oxides classified ? Give two examples of each type.

Explanation

### Step-by-Step Solution:

1. **Introduction to Oxides**:
Oxides are compounds formed by the combination of oxygen with other elements. They can be classified based on their acid-base characteristics.

2. **Classification of Oxides**:
Oxides are classified into four main types:
- **Acidic Oxides**
- **Basic Oxides**
- **Amphoteric Oxides**
- **Neutral Oxides**

3. **Acidic Oxides**:
- **Definition**: Acidic oxides are generally formed from non-metals and can react with water to form acids. They are acidic in nature.
- **Examples**:
- Sulfur Dioxide (SO₂)
- Carbon Dioxide (CO₂)
- Sulfur Trioxide (SO₃)

4. **Basic Oxides**:
- **Definition**: Basic oxides are typically formed from metals and can react with acids to form salts and water. They are basic in nature.
- **Examples**:
- Calcium Oxide (CaO)
- Magnesium Oxide (MgO)
- Sodium Oxide (Na₂O)

5. **Amphoteric Oxides**:
- **Definition**: Amphoteric oxides can act as both acids and bases. They can react with both acids and bases.
- **Examples**:
- Zinc Oxide (ZnO)
- Aluminum Oxide (Al₂O₃)

6. **Neutral Oxides**:
- **Definition**: Neutral oxides do not exhibit acidic or basic properties. They do not react with acids or bases.
- **Examples**:
- Carbon Monoxide (CO)
- Nitrous Oxide (N₂O)
- Nitric Oxide (NO)

### Summary:
In summary, oxides can be classified into four types based on their acid-base characteristics: acidic oxides (e.g., SO₂, CO₂), basic oxides (e.g., CaO, MgO), amphoteric oxides (e.g., ZnO, Al₂O₃), and neutral oxides (e.g., CO, N₂O).
