Name the type of crystal systems of NaCl and Borax.

Explanation

To determine the types of crystal systems for NaCl and Borax, we can follow these steps:

### Step 1: Identify the Crystal Structure of NaCl
- NaCl (sodium chloride) is known to have a cubic crystal structure. Specifically, it forms a face-centered cubic (FCC) lattice.

### Step 2: Describe the Characteristics of the Cubic Crystal System
- In a cubic crystal system, all three axes (A, B, and C) are of equal length, and all three angles (α, β, and γ) are equal to 90 degrees.
