FAQs on Packing Efficiency: Cubic-Close Packed Structures Video Lecture - Chemistry Class 12 - NEET
| 1. What is packing efficiency in the context of cubic-close packed structures? |  |
Ans. Packing efficiency refers to the percentage of space occupied by atoms or molecules in a given structure. In cubic-close packed structures, such as metals, the packing efficiency is determined by the arrangement of atoms in a unit cell. It is calculated by dividing the volume occupied by the atoms by the total volume of the unit cell, and then multiplying by 100.
| 2. How is the packing efficiency calculated in cubic-close packed structures? | |
Ans. The packing efficiency in cubic-close packed structures is calculated by dividing the volume occupied by the atoms by the total volume of the unit cell, and then multiplying by 100. In these structures, each atom is surrounded by 12 nearest neighbors, forming a close-packed arrangement. The packing efficiency is typically around 74%.
| 3. What are the advantages of cubic-close packed structures in terms of packing efficiency? | |
Ans. Cubic-close packed structures have a high packing efficiency, meaning that a large percentage of the available space is occupied by atoms or molecules. This leads to high density and strong bonding between the atoms, resulting in materials with desirable properties, such as strength, hardness, and conductivity.
| 4. Can packing efficiency be greater than 100% in cubic-close packed structures? | |
Ans. No, packing efficiency cannot be greater than 100% in any structure, including cubic-close packed structures. Packing efficiency is a measure of how efficiently atoms or molecules are arranged within a given space. It is always expressed as a percentage, where 100% represents the maximum possible packing efficiency.
| 5. How does packing efficiency affect the properties of materials in cubic-close packed structures? | |
Ans. The packing efficiency in cubic-close packed structures directly influences the density and bonding strength of the material. A high packing efficiency leads to a high density, which is important for materials like metals that require strength and durability. Additionally, the close-packed arrangement of atoms in these structures promotes strong atomic bonding, resulting in materials with desirable mechanical, electrical, and thermal properties.
