Name the parameters that characterized a unit cell.

Explanation

To characterize a unit cell in solid-state chemistry, we need to identify two main parameters: edge lengths and interaxial angles. Here’s a step-by-step breakdown of these parameters:

### Step 1: Identify Edge Lengths
- A unit cell has three edge lengths, which are denoted as:
- **a**: Length of the edge along the x-axis.
- **b**: Length of the edge along the y-axis.
- **c**: Length of the edge along the z-axis.
