What is shape of following crystals?
`KNO_3`

Explanation

To determine the shape of the crystals of potassium nitrate (KNO₃), we can follow these steps:

### Step 1: Understand the Chemical Composition
Potassium nitrate (KNO₃) consists of potassium (K), nitrogen (N), and three oxygen (O) atoms. The nitrate ion (NO₃⁻) is a polyatomic ion where nitrogen is at the center bonded to three oxygen atoms.

**Hint:** Identify the components of the compound to understand its structure.
