An octahedral void is _______times larger than a tetrahedral void.

Explanation

To determine how many times larger an octahedral void is compared to a tetrahedral void, we can use the radius ratio rule. Here’s a step-by-step solution:

### Step 1: Understand the Definitions
- **Tetrahedral void**: A type of void in a crystal lattice that is formed when four atoms surround a central void, forming a tetrahedron.
- **Octahedral void**: A type of void in a crystal lattice that is formed when six atoms surround a central void, forming an octahedron.

### Step 2: Identify the Radius Ratio Ranges
Using the radius ratio rule, we can identify the ranges for different types of voids:
