The valency of the carbonate radical is

Options

A. 1
B. 2
C. 3
D. 4

Explanation

To determine the valency of the carbonate radical, we need to analyze the carbonate ion, which is represented as \( \text{CO}_3^{2-} \).

### Step-by-Step Solution:

1. **Identify the Chemical Formula**: The carbonate radical is represented by the formula \( \text{CO}_3^{2-} \).

2. **Determine the Charge**: The formula \( \text{CO}_3^{2-} \) indicates that the carbonate ion carries a charge of -2.

3. **Define Valency**: Valency refers to the combining capacity of an element or radical, which is often represented by the charge of the ion.

4. **Conclude the Valency**: Since the carbonate ion has a charge of -2, we can conclude that the valency of the carbonate radical is 2.

### Final Answer:
The valency of the carbonate radical is 2.
