Cubic close packing arrangement is also referred to as:

Options

A. Hexagonal close packing
B. Face centred cubic
C. Body centred cubic
D. None of these

Answer

To determine what the cubic close packing (CCP) arrangement is also referred to as, we can follow these steps:

### Step 1: Understand the Terms
Cubic close packing (CCP) is a specific arrangement of atoms in a crystal structure. It is essential to know the various types of packing arrangements in solid-state chemistry.

**Hint:** Familiarize yourself with the definitions of different packing arrangements like FCC, BCC, and HCP.

### Step 2: Identify the Options
The options provided are:
- Hexagonal close packing (HCP)
- Face centered cubic (FCC)
- Body centered cubic (BCC)
- None of these

**Hint:** Write down the abbreviations and full names of each option for clarity.

### Step 3: Recall the Characteristics of CCP
Cubic close packing is characterized by the arrangement of atoms in a way that maximizes space efficiency. In the case of CCP, atoms are arranged at the corners and the centers of each face of the cube.

**Hint:** Remember that CCP is synonymous with the face-centered cubic arrangement.

### Step 4: Analyze the Options
- **Hexagonal close packing (HCP)** is a different arrangement and not the same as CCP.
- **Face centered cubic (FCC)** is another name for cubic close packing.
- **Body centered cubic (BCC)** is a distinct arrangement and does not refer to CCP.
- **None of these** is not applicable since we have identified FCC as a valid option.

**Hint:** Compare the definitions of FCC and CCP to see their similarities.

### Step 5: Conclusion
From the analysis, we conclude that cubic close packing is also referred to as face centered cubic (FCC).

**Final Answer:** The cubic close packing arrangement is also referred to as **Face Centered Cubic (FCC)**.
