ABCABC... type of arrangement of different layers, in a closest packed structure is called:
Correct answer: D. Cubic Close Packing
- A. Hexagonal Close Packing
- B. Body-centered Cubic Packing
- C. Simple Cubic Packing
- D. Cubic Close Packing
Explanation
In a CCP structure, the layers of atoms or ions are indeed stacked in a manner where each layer is positioned directly above the preceding layer, following the sequence ABCABC. This results in a cubic pattern when viewed from the top. This arrangement is commonly found in many metallic crystal structures, including those of elements like copper and aluminum.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
