Question

The example of hexagonal closed packed structure is​

Answer 1

Answer:

The Hexagonal Close-Packed (HCP) unit cell can be imagined as a hexagonal prism with an atom on each vertex, and 3 atoms in the center. It can also be imagined as stacking 3 close-packed hexagonal layers such that the top layer and bottom layer line up. HCP is one of the most common structures for metals. HCP has 6 atoms per unit cell, lattice constant a = 2r and c = (4√6r)/3 (or c/a ratio = 1.633), coordination number CN = 12, and Atomic Packing Factor APF = 74%. HCP is a close-packed structure with AB-AB stacking.

Answer 2

Answer:

Example of hexagonal closed packed structure are cobalt cadmium, zinc

Explaination:

Hexagonal closed packing.

• The hexagonal close-packed (HCP) structure is a crystal lattice arrangement in which the basic repeating unit is a hexagonal arrangement of spheres.
• In this arrangement, the close packing of spheres results in a dense packing and a high coordination number (12), meaning that each sphere is surrounded by 12 neighboring spheres.

• The HCP structure is commonly found in metals such as zinc, magnesium, and titanium, and is also seen in some inorganic compounds, such as beryllium oxide.

• It has a higher packing density compared to the cubic close-packed (CCP) structure, and the hexagonal arrangement of spheres allows for more efficient packing compared to the cubic arrangement. This results in a stronger crystal lattice and improved mechanical properties in materials that adopt an HCP structure.
