Potassium crystallizes with a

Options

A. Face-centred cubic lattice
B. Body-centred cubic lattice
C. Simple cubic lattice
D. Orthorhombic lattice

Answer

To determine how potassium crystallizes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Element**: Recognize that potassium is an alkali metal. Alkali metals include lithium, sodium, potassium, rubidium, and cesium.

2. **Understand Crystal Structures**: Familiarize yourself with the common crystal structures of metals. Alkali metals and certain other metals typically crystallize in specific lattice structures.

3. **Determine the Lattice Structure for Potassium**: Among the alkali metals, potassium specifically crystallizes in a body-centered cubic (BCC) lattice structure.

4. **Conclusion**: Therefore, potassium crystallizes with a body-centered cubic lattice.

### Final Answer:
Potassium crystallizes with a body-centered cubic (BCC) lattice.
