Question

define in detail about close packing in crystal ​

Answer 1

Answer:

Close Packing in €rystal:

Close packing in crystals refers to space efficient arrangement of constituent particles in a crystal lattice. ... So the unit cell of a lattice is a cubic shape. Now when we stack spheres in the cell, there will always be some empty spaces.

The term "closest packed structures" refers to the most tightly packed or space-efficient composition of crystal structures (lattices). Imagine an atom in a crystal lattice as a sphere. While cubes may easily be stacked to fill up all empty space, unfilled space will always exist in the packing of spheres.

The most efficient conformation atomic spheres can take within a unit cell is known as the closest packing configuration. Densely packed atomic spheres exist in two modes: hexagonal closest packing (HCP) and cubic closest packing (CCP).
