Formation of both tetrahedral and octahedral voids

Vedclass · Answer

(C) When we place a second layer over the first layer such that the spheres of the second layer are placed in the depressions of the first layer,voids are formed.- $Tetrahedral$ $voids$ are formed when a sphere of the second layer rests above the triangular void of the first layer.- $Octahedral$ $voids$ are formed when the triangular voids of the first layer and the second layer align such that they do not overlap,creating a space surrounded by $6$ spheres.- Thus,both $tetrahedral$ and $octahedral$ voids are formed in a $3D$ close-packed structure.

Explain the formation of voids during the transition from a two-dimensional hexagonal close-packed layer to a three-dimensional close-packed structure.

In a compound formed by atoms $A$ and $B$, atoms $A$ form a cubic close-packed $(CCP)$ structure, while atoms $B$ are located at the center of each edge. If the edge length of the cubic unit cell is $115 \ pm$, the distance of atom $A$ from the center of the cube is .......... $pm$.

Assertion : In close packing of spheres,a tetrahedral void is surrounded by four spheres whereas an octahedral void is surrounded by six spheres.
Reason : $A$ tetrahedral void has a tetrahedral shape whereas an octahedral void has an octahedral shape.
