What type of packing is observed in hexagonal close-packed (HCP) structures? (2023)
Step 1: Understand that HCP stands for hexagonal close-packed, which is a way atoms are arranged in a solid.
Step 2: Learn that in HCP structures, the atoms are packed closely together to maximize space efficiency.
Step 3: Recognize that the packing arrangement follows a specific pattern.
Step 4: Identify that the pattern in HCP is called ABCABC, meaning the layers of atoms are stacked in a repeating sequence of three different arrangements.
Step 5: Visualize that in the first layer (A), atoms are placed in a specific arrangement, then in the second layer (B), they are placed in a different arrangement, and in the third layer (C), they return to a new arrangement that fits into the gaps of the first layer.
