Define packing efficiency of stablest arrangement
Answers
Answer:
The packing efficiency is the fraction of the crystal or unit cell actually occupied by the atoms. It is impossible to pack spheres without having some empty space between them. Packing efficiency = area of the spheres in the unit cell / total area of unit cell
Explanation:
The packing efficiency is the fraction of the crystal or unit cell actually occupied by the atoms. It is impossible to pack spheres without having some empty space between them. Packing efficiency = area of the spheres in the unit cell / total area of unit cell.The volume of the unit cell is given as. Therefore, packing efficiency of BCC is 68.04%. It must always be less than 100% because it is impossible to pack spheres (atoms are usually spherical) without having some empty space between them.
