Give the structural formula of the potassium tetrafluoridoborate (III).

Explanation

To derive the structural formula of potassium tetrafluoridoborate (III), we can follow these steps:

### Step 1: Identify the Components
The name "potassium tetrafluoridoborate (III)" indicates that we have:
- Potassium (K)
- Tetrafluoride (F4) which means there are four fluoride ions (F⁻)
- Borate (B) which indicates that boron (B) is the central atom and is in the +3 oxidation state.
